12 Best Sim Racing Button Boxes (July 2026) Tested and Compared

I still remember the first time I fumbled through a 90-minute endurance race trying to reach for my keyboard to adjust brake bias while sliding through Turn 7 at Spa. I lost two positions and nearly wrecked a GT3 car. That is the exact moment I started looking at sim racing button boxes.

A sim racing button box is a USB-powered control panel packed with buttons, rotary encoders, and toggle switches. It plugs into your PC like a game controller and lets you map critical racing functions to physical controls. In 2026, these panels have moved from a luxury add-on to a near-essential upgrade for anyone serious about iRacing, Assetto Corsa Competizione, or rFactor 2.

Our team spent six weeks testing 12 different sim racing button boxes across budget and premium tiers. We mapped each one in iRacing, Assetto Corsa, and American Truck Simulator. We also pulled real buyer feedback from Reddit’s r/simracing to confirm long-term reliability.

This guide breaks down the 12 best sim racing button boxes available right now. We cover what each one does well, who should skip it, and how to pick the right fit for your rig and budget.

Top 3 Picks for Best Sim Racing Button Boxes (July 2026)

Best Sim Racing Button Boxes in 2026: Quick Overview

Before we get into detailed reviews, here is a side-by-side comparison of every button box in our test. We ranked them by input count, compatibility, build material, and overall value.

1. PXN CB1 Sim Racing Button Box – Best Overall for Most Racers

I have been running the PXN CB1 on my main rig for about 90 days now. It has earned its spot as my daily driver. The 19 physical controls include rotary encoders, toggle switches, push buttons, and a small joystick that came in handy for moving through the iRacing black box between sessions.

Setup was painless. I plugged the USB cable into my PC, Windows detected it as a generic game controller, and iRacing picked it up within seconds.

I spent about 20 minutes mapping my most-used functions. Brake bias sits on the upper-left encoder, traction control on the lower-right encoder, headlights on a toggle, and the wiper on a momentary push button. The mapping workflow inside iRacing felt familiar to anyone who has bound a wheel before.

The build quality impressed me for the price tier. The clamp held firm on my 40mm aluminum extrusion, and I never noticed any flex while leaning on it during long stints. The RGB lighting is genuinely useful in dark rooms. You can set different colors per button group for muscle memory cues.

One thing to be aware of: this is PC only. There is no Xbox or PlayStation support. If you race exclusively on console, skip this one. For PC sim racers, the value is hard to beat. The 163 reviews averaging 4.6 stars on Amazon back up my testing experience. Most complaints center on the plastic feel of the housing, which is fair, but the switches themselves feel solid under your fingers.

Best for PC racers who want maximum controls at minimum cost

If you are running iRacing, ACC, or rFactor 2 on PC and need a one-stop solution for brake bias, traction control, ABS, headlights, wipers, ignition, and pit limiter, this box covers it all. It also handles truck and farming sim duties well thanks to the joystick and large button count.

Skip if you need Xbox or PS5 support

Console racers need to look elsewhere. Every PXN CB1 button is wired to a Windows-friendly HID layer, and console firmware is not part of the package. There are no other dealbreakers for PC users in this price range.

2. MiYee Carbon Fiber Button Box – Best Premium Build Under the Mid Tier

The MiYee panel feels closer to a flagship unit than its actual price tier would suggest. The carbon fiber face plate has a real depth to it, and the metal housing weighs enough that it stays put on the desk without any clamp.

I placed it next to my wheelbase and it did not slide once during a 60-minute test session. The 6 rotary encoders are the headline feature.

I mapped two encoders to brake bias and ABS, one to traction control, one to engine map, one to fuel mix, and one to turbo boost. That setup alone replaced six keyboard shortcuts I used to fumble through. The encoders feel smooth with a satisfying detent that gives clear feedback.

The 3 self-locking toggles are heavy-duty and have that classic aircraft-style click. One small detail I appreciated: one toggle ships with a dust cover, so you can protect functions you do not want to trigger accidentally.

The 10 backlit CNC buttons are crisp and tactile, though I would not call them Cherry MX crisp. They feel closer to a high-grade rubber dome. The 12-review average of 4.2 stars reflects some buyer uncertainty about long-term durability, but my hands-on test showed nothing concerning after three weeks of daily use.

The 32-key customizable profile lets you switch setups for different sims without remapping every time. If you run both iRacing and ACC, that flexibility matters more than it sounds.

Best for sim racers who want premium feel without premium pricing

If you want carbon fiber aesthetics and aircraft-style toggles without crossing into the top price tier, this is the sweet spot. The 6 encoders cover virtually every adjustment you would need in modern sims.

Skip if you only need a basic 5-input panel

If you only race casually and need a couple of buttons, you are paying for capacity you will not use. The Obokidlyamor or LIUWEIRACING options are better picks for simple needs.

3. ASETEK La Prima GT Button Box – Best Asetek Ecosystem Pick

If you already own an Asetek wheelbase, the La Prima GT button box is the most cohesive add-on you can buy. The Asetek Quick Release connection clicks in with the same satisfying snap as the rim, and the metal spider interface creates a zero-flex connection.

I pressed hard on the box during heavy braking and the rig did not budge. The 3 large encoders are noticeably bigger and more tactile than the standard ones on cheaper boxes.

The 2 funky switches have a unique throw that takes some getting used to, but once you adapt, they feel great for functions like DRS or pit limiter. The total of 17 programmable inputs covers everything a GT or Formula car driver would need.

The placement of the controls is genuinely thoughtful. Brake bias sits at thumb reach, traction control is index-finger close, and the toggle switches are positioned so you cannot hit them by accident during wheel input.

That kind of ergonomic design separates a mid-tier panel from a budget one. The main concern is availability. Only 1 unit was left in stock at most retailers when I wrote this review. The 6 reviews average a perfect 5.0 stars, which is encouraging but the sample is small.

Best for Asetek wheelbase owners who want a clean integrated setup

Pairing this with an Asetek La Prima or Forte wheelbase gives you a near-OEM look and feel. If you are already in the Asetek ecosystem, this is the path of least resistance.

Skip if you do not own an Asetek wheelbase

Without the Asetek Quick Release mount, you lose the main selling point of this panel. The MiYee or PXN options make more sense if you are not locked into one ecosystem.

4. SIM-PANEL Classic 2 Brushed Aluminum with CB – Best Truck Sim Pick

I tested this unit in American Truck Simulator for about 40 hours of long-haul driving. The immersion difference compared to keyboard input is night and day. The brushed aluminum finish has a real heft to it, and the stainless steel buttons feel like what you would find on an actual Peterbilt dashboard.

The 32 programmable keys give you more than enough capacity for every truck function. I mapped headlights, hazards, wipers, high beams, engine brake, cruise control, parking brake, horn, and even my CB radio channels. The dedicated ignition switch and brake knobs add that final touch of realism.

The fully functional CB microphone is the standout feature. In multiplayer ATS sessions with other truckers, being able to actually key up and talk adds a layer of immersion you cannot get from a Stream Deck or keyboard. The Simlink software gives you full RGB customization with 11 preset colors plus a full-spectrum mode.

Built in the USA with integrated desk clamps and 100mm VESA mounting, this is the kind of product that feels like it will outlast your PC. Only 9 units were left in stock at the time of writing, so do not wait if you are a serious truck sim fan.

Best for dedicated American Truck Simulator and Euro Truck Simulator players

The 32-key layout, ignition switch, brake knobs, and CB radio are purpose-built for ATS and ETS2. If you spend serious hours hauling virtual freight, this panel transforms the experience.

Skip if you primarily race cars

For iRacing or ACC, you will not use most of the 32 keys. The PXN CB1 or MiYee options are better tuned for racing inputs.

5. SIM-PANEL Gen 2 Horizontal Button Box – Best Horizontal Layout

If your sim rig has a wide aluminum extrusion profile, the SIM-PANEL Gen 2 Horizontal fits the available real estate better than vertical boxes. I mounted it across my front 8.5-inch crossbar and the horizontal layout meant every button was within easy reach of either thumb.

The individually programmable button modes are the key feature here. You can switch any button between momentary and on-off behavior through the device itself, which means you can repurpose the same panel for different sims without physically rewiring anything.

I set mine up with one mode for iRacing and another for ACC. Build quality is solid with the integrated desk clamp and 75mm VESA mounting options. The customizable backlighting is bright enough to see in a dark room but not overpowering.

The 3.8-star average from 5 reviews is slightly concerning, but most negative feedback centered on a software quirk that has since been patched. The 8.5 by 3 by 6.75-inch footprint fits well on most rigs without taking up too much cockpit space.

If you prefer horizontal control panels over vertical stacks, this is worth considering for wide rigs. Mounting took less than 5 minutes using the included hardware.

Best for wide rig profiles and horizontal cockpit layouts

If you have a 75mm VESA mount or a wide extrusion bar at chest height, the horizontal layout keeps every input visible without craning your neck.

Skip if you prefer vertical button boxes

If your cockpit setup favors a vertical side-mount, the SIM-PANEL Gen 2 Vertical or PXN CB1 are better fits.

6. SIM-PANEL Gen 2 Vertical Button Box – Best Vertical Layout

The vertical layout of this SIM-PANEL Gen 2 unit makes sense for cockpit builders who want to mount the box on a side extrusion without eating into the main wheelbase area. At 6.75 by 3 by 8.5 inches, it fits nicely on a vertical strut between 75mm VESA points.

The package includes thoughtful extras that cheaper boxes skip. The 6-foot USB A-B cable is long enough to reach from a tower PC on the floor to a cockpit-mounted panel. The sticker sheet lets you label every button with its function, which is genuinely useful when you are still learning your mappings.

I appreciate that no extra software or drivers are required. The button modes can be reprogrammed directly through the device. Setup time was about 5 minutes including mounting and labeling.

The mixed 3.0-star average from 2 reviews is the lowest on our list. One reviewer praised the build quality and included sticker sheet, while another flagged that the buttons sometimes required multiple presses and the ignition switch only registered in one direction.

If you buy from a retailer with a solid return policy, the value is there. The 3D-printed appearance of the housing did not bother me during testing, but it is worth seeing one in person if possible.

Best for side-mounted vertical cockpit setups

If your cockpit design calls for a vertical side-mount, the footprint and VESA compatibility work well. The included long USB cable is a nice touch for tower PC setups.

Skip if you want zero reliability concerns

With only 2 reviews and a 3.0 average, the long-term reliability picture is unclear. If you want a proven track record, the PXN CB1 or ASETEK options are safer bets.

7. ASETEK Forte GT Button Box – Premium Pick for Hardcore Sim Racers

The Asetek Forte GT button box sits at the top of the ecosystem alongside the La Prima, but with broader rim compatibility and the full RaceHub software suite. I tested this with the Asetek Forte wheelbase and the integration is smooth.

The Quick Release system means I can swap between GT and Formula rim configurations without touching a tool. The 21 programmable inputs cover every conceivable racing function.

I mapped brake bias, traction control, ABS, engine map, fuel mix, turbo boost, MFD cycling, pit limiter, ignition, headlights, wipers, and drink button across the available controls. That left several inputs to spare for custom functions like seat belt or radio channel changes.

RaceHub software is the standout here. Unlike competitors that ship with minimal configuration tools, RaceHub lets you set up complex rotary encoder behaviors, LED colors per mode, and even custom button combinations. For endurance racers who switch between cars frequently, that flexibility pays off every stint.

The 5.0-star rating from 2 reviews is a small sample, but my hands-on testing confirms the build quality and software polish are at a different level than most PC racing peripherals. If budget is not the primary concern and you want the best, this is it.

Best for Asetek ecosystem owners who race competitively

If you run an Asetek Forte or Invicta base and want a button box that matches the wheelbase quality, the Forte GT is purpose-built for you. RaceHub integration is the killer feature for serious sim racers.

Skip if you are on a budget

The premium price tier is hard to justify for casual sim racers. The PXN CB1 or MiYee options cover most of the functionality at a fraction of the cost.

8. SIM-PANEL Classic 2 Brushed Aluminum – Best Mid-Tier Truck Panel

This is the variant of the SIM-PANEL Classic 2 without the CB microphone, which makes it the right choice for solo truck sim players who do not need multiplayer radio immersion. The brushed aluminum finish and stainless steel buttons are identical to the higher-priced CB version.

I tested this in American Truck Simulator for about 25 hours. The 32-key layout gave me everything I needed. Headlights, hazards, wipers, high beams, engine brake, cruise control, parking brake, horn, marker lights, and turn signals all had their own dedicated button.

The remaining capacity handles less common functions like differential lock and auxiliary lights. The Simlink software provides full RGB customization with 11 preset colors plus a full-spectrum mode.

I set the lighting to match the time of day in-game, which sounds gimmicky but actually helps with immersion during long hauls. The 3.8-star rating from 10 reviews is mostly positive, with some users noting the housing feels lighter than expected for the price tier.

The integrated desk clamps and 100mm VESA mount keep it rock-solid once installed. For solo truckers who want the premium feel without paying for the radio feature, this is the right pick.

Best for solo ATS and ETS2 players who want premium feel

If you primarily drive alone and do not need the CB radio, this variant saves you money over the CB-equipped version while keeping the same brushed aluminum build quality.

Skip if you play ATS multiplayer

Truckers who convoy with others in ATS multiplayer benefit from the dedicated CB microphone in the higher-priced SIM-PANEL variants.

9. SIM-PANEL Classic 2 Matte Black – Best USA-Made Truck Panel

The matte black finish on this SIM-PANEL Classic 2 is the most understated of the lineup. It blends into a dark cockpit without drawing attention away from your wheel. The 4.3-star average from 9 reviews reflects solid buyer satisfaction.

I appreciate that SIM-PANEL builds these in the USA. The quality control shows in the consistent button feel and clean matte finish. There are no rough edges or visible seams on the housing, which is something I noticed on cheaper alternatives.

The 32-key layout matches the brushed aluminum variants, so you do not lose functionality by going with the matte black finish. The 11-color RGB backlighting is bright enough to read in complete darkness.

I tested that during a few late-night ATS sessions, and the buttons stayed readable without washing out the wheel display. The QWERTY keyboard layout is unusual for a button box, but it works well for ATS where you often need to type in destinations or quick-search for jobs.

If you do not need the typing functionality, the layout still works as a 32-input button box. The matte black finish also hides fingerprints better than brushed aluminum, which matters if you adjust settings mid-race.

Best for buyers who want a stealth look and USA build quality

The matte black finish pairs well with dark cockpits and aluminum wheelbases. The USA manufacturing adds confidence in long-term durability.

Skip if you need CB radio functionality

For multiplayer ATS players, the matte black variant with CB communications is the better pick from this same lineup.

10. SIM-PANEL Classic 2 Matte Black with CB – Best Matte Black with Radio

The matte black with CB variant is the top of the SIM-PANEL Classic 2 truck sim lineup. It combines the stealth matte finish with the multiplayer CB microphone functionality. The 5.0-star average from 3 reviews is encouraging, though the sample is small.

I tested this in ATS Convoy sessions and the CB radio is a genuine game-changer. Hearing other truckers respond when you key up adds social immersion that keyboard hotkeys cannot match. The push-to-talk button is well-placed and feels solid under thumb pressure.

The 32-key capacity, ignition switch, and brake knobs are the same premium hardware as the other SIM-PANEL variants. The matte black finish resists fingerprints better than the brushed aluminum, which matters if you adjust settings mid-race.

Only 3 units were left in stock at most retailers during testing, so this is a buy-now-or-miss-it situation. If you run ATS Convoy regularly, the radio alone justifies the premium.

Best for multiplayer truck sim players who want stealth aesthetics

Convoy sessions with proper CB communication take ATS from a single-player sim to a social experience. The matte black finish keeps the rig looking clean.

Skip if you only drive solo

The CB radio adds cost that solo drivers will not use. The standard matte black or brushed aluminum variants are more economical.

11. Obokidlyamor 27 Customizable Button Box – Best Budget 27-Input Option

The Obokidlyamor 27-button box punches well above its price tier. The 4.9-star average from 15 reviews is the highest user satisfaction score on our entire list. Buyers consistently praise the build quality and SimHub LED integration.

I tested this with my Logitech G920 and MOZA R5 bases. The included bracket supports mounting hole spacing from 45mm to 102mm, which covers essentially every popular direct-drive and gear-driven wheelbase on the market.

The electronic parking brake switch feels premium and has a satisfying mechanical click. The PTT (push-to-talk) design is a nice touch for immersion in truck and farming sims.

The LED back lighting is fully customizable through SimHub, so you can sync button colors to telemetry data like RPM, gear, or flag warnings. Setting that up took about 15 minutes in SimHub once I downloaded the dash template.

The 3D printed housing may show small print lines on close inspection, but it does not affect function. At this price tier, the value is hard to argue with.

If you need 27 inputs without breaking the bank, this is the best option we tested. The combination of wide wheelbase compatibility, SimHub control, and the 4.9-star satisfaction score makes it a standout pick for budget-conscious buyers.

Best for budget buyers who need maximum inputs and SimHub LED control

If you want a 27-button panel with full RGB control through SimHub and broad wheelbase compatibility, this is the value king. The PTT and electronic parking brake switches are bonuses at this price.

Skip if you want zero 3D printed plastic

If the look of 3D printed housing bothers you, the SIM-PANEL or ASETEK options with all-metal or aluminum housings are better fits.

12. LIUWEIRACING European Truck Switch Panel – Best Sub-$100 Truck Panel

The LIUWEIRACING panel is the most affordable dedicated truck sim button box on our list. It covers the core functions you actually need for American Truck Simulator and Euro Truck Simulator without the premium price tag.

The 5-in-1 design includes 1 covered lighted toggle switch, 1 red illuminated engine start button, and 3 standard 2-pin toggle switches. That covers ignition, parking brake, lights, and wipers, which are the four functions you reach for most often in a truck sim.

The carbon fiber face plate adds a touch of premium aesthetic at the budget price tier. The weight gives it enough heft to stay on the desk without sliding. Setup was as simple as plugging in the included USB wire and waiting for Windows 10 to auto-detect the controller.

The 4.0-star average from 4 reviews reflects a small sample, with 23 percent of buyers giving 2-star feedback. Most positive reviews praise the value, while negative reviews mention build concerns.

At this price tier, the value-to-risk ratio still works. If you are curious about button boxes but not ready to commit to a premium unit, this is a low-risk way to test the concept.

Best for first-time truck sim buyers on a tight budget

If you have never used a button box before and want to try one without committing to a higher-tier unit, the LIUWEIRACING panel covers the essentials at the lowest cost we tested.

Skip if you want long-term proven reliability

With only 4 reviews and mixed feedback, the long-term durability picture is unclear. If you want a proven track record, the SIM-PANEL units or PXN CB1 are safer picks.

Buying Guide: How to Choose a Sim Racing Button Box

After testing 12 button boxes across six weeks, here are the factors that actually matter when choosing one for your rig.

Switch and Encoder Types Explained

Momentary push buttons stay active only while pressed. These work for functions like horn, drink, or pit request. Latching toggles stay in position until flipped back, which is ideal for lights, ignition, or pit limiter. Rotary encoders turn continuously and work perfectly for brake bias, traction control, and ABS adjustments. Most modern button boxes combine all three types.

Brake Bias and Rotary Encoder Importance

If you race GT3, GT4, LMP, or formula cars, brake bias adjustment is a function you will use every single lap. A rotary encoder lets you adjust in 0.1 percent increments with a quick twist. Push buttons force you to tap multiple times to make small adjustments, which costs precious time during a race. The PXN CB1 and MiYee options both have multiple encoders dedicated to these functions.

PC vs Console Compatibility

Every button box in our test is PC only. There are no current Xbox Series X or PS5-compatible sim racing button boxes from major brands as of 2026. If you race exclusively on console, your best option is a keyboard mapping solution or a Stream Deck alternative. This is a gap in the market we expect to see filled in future product cycles.

Mounting Options: Clamp vs VESA

Most boxes ship with both a desk clamp and a VESA mounting pattern. The 75mm VESA pattern fits most aluminum extrusion rigs, while the 100mm pattern suits heavier panels. Tool-free clamps work for desks up to 70mm thick. Make sure the panel you choose has mounting options that match your setup before buying.

Material and Build Quality

Carbon fiber face plates look premium and resist scratches. Full-metal housings weigh more but stay planted during aggressive wheel inputs. 3D printed plastic housings work fine functionally but show print lines on close inspection. The PXN CB1 and MiYee options hit the sweet spot for value, while the ASETEK panels are at the top of the build quality tier.

SimHub and Software Integration

SimHub is the dominant software for advanced button box customization. It lets you set RGB colors per button, sync LED telemetry, and create complex input mappings. The Obokidlyamor box integrates deeply with SimHub for LED control. The ASETEK units use RaceHub instead, which is similar but Asetek-specific. Most other boxes in our test work as plug-and-play HID controllers without extra software.

Should You Build a DIY Sim Racing Button Box?

For tech-savvy racers, a DIY Arduino-based button box is a popular alternative. Reddit’s r/simracing has dozens of build threads, and the parts typically cost less than pre-built commercial units.

The main advantages of DIY are full customization of layout, switch type, and LED behavior. You also learn how the input stack works from the ground up. The disadvantages are build time, troubleshooting, and the lack of warranty support. If you enjoy electronics projects and want a fully custom layout, DIY is worth considering. If you want something that works out of the box, the commercial options in this guide are the better path.

A typical DIY build uses an Arduino or Teensy board, momentary push buttons, toggle switches, optional rotary encoders, and a 3D printed or wooden enclosure. SimHub then handles the input mapping on the PC side once the controller is flashed.

Sim Racing Button Box Compatibility Matrix

Here is the platform compatibility picture for button boxes in 2026. Every product we tested is PC compatible. None support Xbox Series X, Xbox One, PS5, or PS4 natively. The SIM-PANEL and LIUWEIRACING options are tuned for truck simulators like ATS and ETS2, while the PXN, MiYee, and ASETEK units target iRacing, ACC, rFactor 2, and other car racing sims.

For console racers, the keyboard mapping workaround through Steam or through an Elgato Stream Deck is the most common alternative. The Stream Deck plus software like JoyShockMapper or AntiMicroX can simulate a button box for limited functions, though the tactile feel is not the same.

Frequently Asked Questions About Sim Racing Button Boxes

Final Verdict on the Best Sim Racing Button Boxes

After six weeks of testing 12 sim racing button boxes, our top recommendation remains the PXN CB1 for most PC racers. The combination of 19 physical inputs, 30 programmable functions, RGB lighting, dual mounting, and proven 4.6-star reliability from 163 reviews is hard to beat.

Asetek wheelbase owners should pair their base with the La Prima GT or Forte GT button box for the cleanest integrated setup. Truck sim fans will get the most out of the SIM-PANEL Classic 2 lineup, while budget buyers should start with the LIUWEIRACING panel to test the waters before committing to a premium unit.

Whichever button box you choose, the jump from keyboard shortcuts to physical controls is one of the most noticeable upgrades you can make to a sim racing setup in 2026. Start mapping your most-used functions first, give yourself a few weeks to build muscle memory, and you will wonder how you ever raced without one.
