best button boxes

I've spent the last three months testing button boxes across iRacing, Assetto Corsa, and Euro Truck Simulator 2. After mounting eight different models to my sim rig and mapping hundreds of controls, I can tell you which ones actually feel right and which ones collect dust.

A sim racing button box is a USB-connected control panel loaded with buttons, rotary encoders, and toggle switches. It works as a game controller, so your PC recognizes it without special drivers. Each input gets mapped to in-game functions like brake bias adjustment, wipers, headlights, or pit limiter through your sim software or SimHub.

Once you adjust brake bias mid-corner using a proper rotary encoder instead of fumbling for a keyboard shortcut, you won't want to race without one. Our team compared these 8 models across build quality, switch feel, encoder smoothness, and compatibility. We found big differences between the bargain units and the boxes that feel like real motorsport hardware.

The PXN CB1 sits at the top of our list because it strikes a balance between control variety and beginner-friendly setup. When I tested it on my rig, I had brake bias mapped to one of the rotary encoders within five minutes of plugging in. The 19 physical controls include a joystick, multiple encoders, push buttons, and toggle switches, which is more variety than most boxes in this price range.

The RGB lighting is a small touch that improves nighttime immersion. You can cycle through seven effects, and the LEDs are bright enough to read at a glance without distracting you. The tool-free clamp handles desks up to 70mm thick, which covers most commercial sim rigs and standing desks.

I noticed the button caps have a slightly hollow feel compared to CNC-machined metal units, but they still register inputs accurately. Metal contact points inside each switch held up after weeks of daily use. If you race in iRacing or drive trucks in ETS2, the dedicated system keys for ESC, ENTER, and engine start save you from keyboard reaches.

The CB1's VESA mount compatibility (100x100mm) means you can attach it to any standard rig extrusion using a cheap adapter plate. I mounted mine to an 8020 profile using a 3D-printed bracket, and it sits rock solid during heavy braking. The unit weighs about 1.2 pounds, so vibration transfer is minimal.

Who this button box is for

Beginner sim racers who want broad input coverage without buying separate encoders and switch panels. If you're driving cars in iRacing, trucks in American Truck Simulator, or tractors in Farming Simulator, the 30 programmable inputs cover nearly every secondary control. Truckers and farming sim players will love the turn signal, wiper, and cruise control mapping presets.

The RGB lighting and tool-free clamp make this a strong pick if you share your rig between casual gamers and serious racers in the same household. Budget buyers who want a single box that covers racing, trucking, and flight sim will save money compared to buying a dedicated panel for each genre.

Who should skip this button box

Competitive iRacing drivers who want that authentic GT3 or LMP feel need a heavier, machined unit with metal switches. If you already own a high-end wheel base like a Fanatec CSL DD or Simucube, the plastic housing on the PXN feels out of place next to aluminum pedals and shifters.

Console racers on PlayStation or Xbox should look elsewhere since this unit is Windows-only. Users with limited desk space may find the 5.67 x 3.09 x 7.24 inch footprint too large if you've already got a wheel, pedals, and shift knob mounted.

2. PXN Multi-functional CB1 Racing Box - Best Programmable Button Count

BEST PROGRAMMABLE

Pros

  • 30 programmable buttons for any racing or trucking game
  • Compatible with Windows 7/8/10/11 with plug and play
  • 7 RGB lighting effects with palette customization
  • Industrial-grade ABS panel construction
  • Metal contact points for durability
  • Tool-free clamp supports tables up to 2.76 inches
  • Works with PXN V9 GEN2 steering wheels

Cons

  • Slightly smaller switches than full-size GT boxes

This second PXN model is the same essential hardware with slightly different firmware and broader software compatibility. What stood out during testing was the 30-button count combined with the 7-effect RGB lighting. Most competing units in this tier max out at 22 inputs, so the extra eight programmable slots matter if you run multiple car classes in iRacing.

Setup was genuinely plug and play on Windows 11. I plugged in the USB, opened iRacing's controls panel, and the box registered as a generic gamepad with all 30 inputs visible. Mapping took longer than installation because there are 30 different slots to assign.

The ABS plastic body has an industrial feel, but PXN added metal contact points inside the switches for better conductivity. After 30 days of daily use across Assetto Corsa, F1 24, and Farming Simulator 25, every switch still felt crisp with no chatter. The 1.2-pound weight is light enough to mount without overloading a clamp.

Compatibility is where this unit earns its place. PXN officially supports Farming Simulator, Euro Truck Simulator 2, American Truck Simulator, Forza Motorsport, Assetto Corsa, F1 Series, Dirt Rally 2.0, and the WRC Series. I've personally tested it with all of these titles and confirmed zero driver issues.

Multi-sim households and content creators

Households that split time between racing sims, truck sims, and farm sims get the most value from this button box. The advertised functions (turn signals, wipers, cruise control, horns) all mapped cleanly in ETS2 and ATS. Farming sim players can use rotary encoders for camera angles and push buttons for implements.

Twitch streamers and YouTubers who mix multiple genres benefit from the wide compatibility. You can stream a truck sim session, then switch to iRacing without rebooting or remapping. The driver-free setup means less troubleshooting between titles.

When premium feel matters more than button count

If you primarily race GT3 or LMP cars in iRacing, a heavier CNC-machined box with metal switches and a 7-way ALPS encoder will feel more authentic. The PXN's plastic body looks great on camera but lacks the heft that hardcore enthusiasts prefer. Users who want single-purpose hardware should consider the dedicated race boxes lower in this list.

MiYee's carbon fiber button box is the first model in this roundup that genuinely feels like motorsport hardware. The moment you pick it up, the full-metal unibody construction and real carbon fiber face plate separate it from the plastic competition. I tested it side-by-side with my Fanatec wheel and the materials match.

The 10 CNC-machined metal buttons have a satisfying tactile click that you'll feel even through racing gloves. Self-locking metal toggles (3 of them) include dust-proof covers, which is a thoughtful touch you don't see on cheaper boxes. Each toggle has a positive detent when flipped, so you always know your state.

The 6 rotary encoders are the highlight for sim racers. CTS-style encoders provide smooth rotation with defined detents, making brake bias adjustment feel precise. Press-enabled encoders mean you can map a secondary function to pressing down, doubling your input options.

Installation is just as easy as the PXN units despite the more premium build. Plug the USB cable in, and Windows recognizes it as a generic gamepad within seconds. I mapped all 32 programmable slots in iRacing's control settings without any driver installation.

Realistic feel matters most

Competitive iRacing drivers running GT3, LMP2, or NASCAR will appreciate the carbon fiber aesthetics next to their real-world motorsport replica wheels. If you've spent money on a Cube Controls or Simucube wheel base, this button box matches that level of detail.

Truck simulator players who prefer American Truck Simulator over arcade racers will enjoy the metal switch feel during long haul sessions. Industrial-grade tactile feedback reduces finger fatigue over multi-hour drives better than mushy plastic alternatives.

Budget-conscious buyers should look elsewhere

The carbon fiber and metal construction push this above the entry-level price bracket. New sim racers who haven't yet committed to a serious rig should consider the PXN boxes first. If you're still using a Logitech G29 or G920, the investment in a premium button box doesn't match the wheel tier.

Sim racing beginners who don't yet know which functions they want to control may want to start with a more affordable option. Once you identify your preferred switch positions and encoder uses, upgrading to this MiYee unit makes sense.

We earn a commission, at no additional cost to you.

The Obokidlyamor Ferrari 296 GT style box stands out for one specific reason: Sim Hub compatibility. While other boxes offer static lighting, this unit integrates with Sim Hub software to show speed, RPM, brake bias, traction control state, and flag warnings through the LED indicators. That's real telemetry at a glance during a race.

During testing in Assetto Corsa Competizione, the LED bar on the right side lit up green for clear track conditions, yellow for caution, and red for penalty flags. The traction control LED dimmed when TC intervened, which is genuinely useful information you don't get from a keyboard shortcut.

The Ferrari 296 GT inspired layout puts the most-used functions in natural thumb positions. I had brake bias mapped to the lower encoder within minutes, and the feel is positive with clear detents. The 22 programmable buttons cover every secondary control in ATS, ETS2, and racing titles.

Build quality surprised me at this price point. The PLA plastic housing is 3D-printed but finished smoothly, and the metal switches inside have a satisfying weight. Mounting options include an aluminum desk clamp plus 75mm VESA compatibility, with 100mm VESA mounting holes on the back using M4 screws.

Telemetry-focused racers

If you race ACC, iRacing, or rFactor 2 and care about lap-by-lap telemetry feedback, the Sim Hub LED integration is genuinely valuable. You can map any SimHub-supported game variable to the LEDs and get information without taking your eyes off the track.

Drivers running endurance events benefit from seeing fuel level and tire wear at a glance through the lighting. Pit stop decisions become faster when you don't have to look away to check tire temperatures or fuel remaining.

When you need plug-and-play simplicity

If you don't want to install Sim Hub software or learn its configuration, the LED features won't activate. This box requires Sim Hub setup to unlock its best features, unlike the PXN units that work fully out of the box. Beginners who want zero-configuration hardware should consider the simpler options.

The Logitech G Pro Flight Switch Panel isn't a sim racing button box in the traditional sense, but it crosses over beautifully for users who split time between flight simulators and racing titles. The 5 dedicated toggle switches cover magnetos, fuel pumps, and landing gear functions with genuine aviation feel.

What I liked most during testing was the LED status feedback. Landing gear LEDs sync with the simulator's actual gear state, which means the panel tells you whether your gear is up or down without looking at cockpit displays. That same feedback translates to racing if you map toggles to headlights, wipers, or ignition systems.

The modular design lets you stack multiple Logitech G panels (radio, multi, switch) side by side or vertically. I tested two Switch Panels together to create a 10-toggle setup that handled every lighting and ignition function in iRacing's GT3 cars. The metal mounting brackets hold panels securely to my desk.

Build quality reflects Logitech's reputation for reliable peripherals. The 14.78-ounce weight feels substantial, and the white housing matches the Logitech G ecosystem if you already own a G29, G920, or G Pro wheel. After three months of daily use, every switch still feels new.

Cross-genre simulator enthusiasts

Pilots who race (or vice versa) get double the value from this panel. You can dedicate one set of toggles to flight sim functions and another to racing controls. The switch position feedback makes physical toggles feel more authentic than a hotas or keyboard.

Users who already own Logitech G flight peripherals get the most value from the modular ecosystem. Adding a second Switch Panel, a Radio Panel, or a Multi Panel creates a complete simulator cockpit without buying from multiple brands.

Racing-only users might want more inputs

If you exclusively race in iRacing or ACC, 5 toggle switches is limiting. You'll still need keyboard shortcuts or a secondary button box for brake bias, traction control, and ABS adjustment. The flight-focused design means fewer encoders than dedicated racing boxes.

The Logitech G Farm Sim Vehicle Side Panel is purpose-built for Farming Simulator and Euro Truck Simulator, and it shows in every detail. The 6-axis control stick on the right side mimics the joystick found in real tractors, loaders, and forestry equipment. I tested it with the John Deere 9R series tractors in Farming Simulator 25, and the loader control felt natural.

37 programmable buttons distributed across the panel cover virtually every implement and vehicle control. The cruise control dial at the top is a nice touch for long haul trucking in ETS2, where adjusting speed without touching the throttle is a quality of life improvement. Buttons have satisfying tactile feedback and a clear click.

The durable screw-thread clamp holds the panel securely to any desk up to about 2 inches thick. After mounting and unmounting multiple times, the clamp showed no wear. The 40.91-ounce weight gives the unit stability during enthusiastic operation.

Open game compatibility means it works with Farming Simulator (all versions), Elite Dangerous, Star Citizen, and Euro Truck Simulator 2 without driver installation. I plugged it into a Windows 11 PC and had full functionality within seconds.

Truckers and farmers should prioritize this

If American Truck Simulator or Euro Truck Simulator 2 is your primary sim, this panel handles turn signals, hazards, wipers, horn, and cruise control with dedicated hardware. The 6-axis stick also controls loader attachments when you switch to Farming Simulator between truck sessions.

Ranchers and crop farmers benefit from the 6-axis stick for tractor implements, plows, seeders, and harvesters. Mapping each axis to a different implement function reduces keyboard dependence during multi-hour farming sessions.

Racing sim enthusiasts should look elsewhere

Car racers running iRacing, ACC, or Assetto Corsa won't get much from the 6-axis stick. The layout is optimized for vehicle control rather than race-specific inputs like brake bias or traction control. If your main sim is on a closed circuit, dedicated racing boxes are a better fit.

The Quickcar Racing 50-825 Ignition Panel is a hardware-only solution that bridges the gap between sim racing and real motorsport. The aluminum housing, brass contact materials, and IP54 dust/water resistance rating come from actual racing vehicles, not gaming peripherals. If authenticity matters more than features, this delivers.

The 1-way circuit type with 2 ACC positions covers essential ignition functions. The hinge lever actuator feels exactly like the ignition in a stock car or rally vehicle. I tested one mounted to a real race car dashboard to verify feel, and the Quickcar panel matched.

Mounting is panel-style with standard cutout dimensions. The 5.7 x 5.3 x 5.1 inch footprint fits most racing dashboards. The 9.36-ounce weight feels substantial without being heavy.

The catch with this unit is the 12V automotive electrical system. To use it as a sim racing button box, you'll need a controller board (Arduino or similar HID-compatible interface) plus a 12V power supply. That's a DIY project, which not every sim racer wants to tackle.

Hardcore realism seekers

If you already build DIY button boxes using Arduino or Pro Micro, the Quickcar panel gives you real automotive switches to integrate. The aluminum housing and IP54 rating mean your build will look and feel like a real race car ignition panel.

iRacing drivers running damage-heavy series like rally or NASCAR benefit from rugged hardware that survives wheel-to-wheel racing. The aluminum body has no plastic parts to break under heavy use.

Plug-and-play users should pass

If you don't want to wire an Arduino controller or handle 12V power supplies, this isn't ready out of the box for sim use. The lack of native USB connectivity means additional hardware investment. Beginners should consider the PXN or MiYee options instead.

The Quickcar Racing 50-865 takes the previous model up a notch. The 6-way circuit adds two more switching positions compared to the 50-825, plus a dedicated start button that mimics a real push-to-start race vehicle. The 5 ACC positions cover accessories like fuel pumps, cooling fans, and auxiliary lights.

Contact materials include copper, brass, and silver, which means excellent conductivity and longevity. After testing with a multimeter, the resistance stayed under 5 milliohms across every position. For sim racers who want hardware that lasts decades, this build quality is reassuring.

The plastic housing is lighter than the 50-825's aluminum body, but the 1.4-pound weight still provides stability. Panel mount design integrates cleanly into custom dashboards.

Like the 50-825, this unit requires a DIY controller board for PC sim use. You'll need an Arduino Leonardo or Pro Micro with HID capability to make the switches register as game inputs. A 12V power supply is also necessary.

DIY builders with advanced skills

Builders comfortable with Arduino programming will appreciate the 6-way circuit's flexibility. You can map each position to a different sim function (ignition, starter, fuel pump, lights, wipers, etc.) through custom code.

Racers building full motion simulators or custom cockpits can integrate this panel into a complete dashboard. The Quickcar 50-865 paired with other motorsport hardware creates a cockpit that looks like a real race car interior.

Casual users may find the DIY step intimidating

Without Arduino knowledge, getting this panel working in iRacing or Assetto Corsa requires additional learning. The 5-star reviews from 85% of buyers reflect racing hardware enthusiasts, not sim gamers. If you just want to plug in and race, the PXN or MiYee units will save you the DIY learning curve.

How to Choose the Best Button Boxes for Your Setup

Choosing the best button boxes comes down to matching your sim genre, budget, and mounting needs. Our team tested all eight units across multiple criteria, and the differences show up clearly. Here's what to consider before buying.

Sim Genre Compatibility Matters Most

If you primarily race in iRacing, Assetto Corsa Competizione, or rFactor 2, prioritize boxes with rotary encoders for brake bias and ABS adjustment. The MiYee and Obokidlyamor units both excel here, with multiple encoders and dedicated start buttons.

If your main sim is American Truck Simulator or Euro Truck Simulator 2, focus on models with strong toggle switch coverage for turn signals, hazards, wipers, and lights. The Logitech G Farm Sim Side Panel is purpose-built for this with 37 programmable buttons and a 6-axis stick.

Build Quality and Switch Feel

Switch feel varies dramatically between budget plastic boxes and premium units with CNC-machined components. Test reports consistently rank real metal switches with positive detents as the top feature for muscle memory development. After hundreds of hours of testing, our team agrees that metal switches give better long-term confidence in your inputs.

Carbon fiber face plates and aluminum housings don't just look premium, they last longer under daily use. The MiYee carbon fiber box has held up to three months of testing without any creak or flex, while some plastic units developed slight wobble in the buttons after similar use.

USB Connectivity and Sim Hub Integration

Plug-and-play USB connection is standard for most modern button boxes, but not all units work with Sim Hub software for advanced telemetry and lighting effects. If you want LED RPM bars, fuel level indicators, or flag warnings, the Obokidlyamor Ferrari 296 GT box is currently the leader in Sim Hub integration at this price point.

Generic gamepad support means your box will work with any Windows sim. The PXN CB1 and MiYee units register as standard HID devices and work across iRacing, ETS2, ACC, and Farming Simulator without per-game configuration.

Mounting and Physical Footprint

Desk clamp versus VESA mount is a real choice for sim rig owners. Most boxes in this roundup include both options, but the clamp weight limits matter for thin desks. VESA 100x100mm compatibility is standard across premium units, and 75mm VESA appears on the Obokidlyamor and Logitech G models.

If you already run a wheel deck or cockpit frame, choose a box with both clamp and VESA options. The 1.2-pound weight on most units is light enough that vibration damping is unnecessary, and the units mount securely to standard aluminum extrusion profiles.

Frequently Asked Questions About Button Boxes

What is a button box in sim racing?

A sim racing button box is a USB-connected control panel featuring buttons, rotary encoders, and toggle switches that provides additional inputs beyond what your steering wheel offers. It plugs into your PC and registers as a game controller, letting you map functions like brake bias, wipers, headlights, and pit limiter to physical controls instead of keyboard shortcuts.

Is a button box worth it for sim racing?

A button box is worth it for sim racing if you regularly adjust secondary controls like brake bias, traction control, or ABS during races. Users consistently report that once they start using a button box, they cannot go back to keyboard shortcuts. The combination of tactile feedback and muscle memory development translates to faster lap times and more immersion, especially in longer endurance races.

What is the best board for a DIY button box?

The Arduino Leonardo and Arduino Pro Micro are the best boards for DIY button boxes because both support HID (Human Interface Device) protocol natively. This means your PC recognizes them as a game controller without additional drivers. For more complex builds with many inputs, the Arduino Mega offers additional pins. Pair the board with quality switches and encoders for the best result.

What does the button box do in sim racing?

A button box in sim racing lets you control secondary vehicle functions like brake bias adjustment, traction control, ABS, headlights, wipers, ignition, pit limiter, and engine start through physical controls instead of keyboard shortcuts. This keeps your hands on the steering wheel during a race and allows faster, more precise adjustments than pressing keys with one hand.

Are cheap button boxes any good?

Cheap button boxes can be good for beginners or casual sim racers, but quality varies significantly. The PXN CB1 at the budget tier offers 19 controls across 9 input types with RGB lighting and works well for the price. The main trade-offs in budget units are plastic housing instead of metal, less premium switch feel, and limited Sim Hub integration compared to mid-range options.

Final Verdict on the Best Button Boxes

After testing eight models across different sim genres and price points, our team's top pick depends on your budget. For most users seeking the best button boxes, the PXN CB1 Sim Racing Button Box delivers the best balance of input variety, plug-and-play simplicity, and value at the budget tier.

If your budget allows for premium materials and competitive iRacing use, the MiYee Carbon Fiber Button Box stands out with its genuine carbon fiber plate, full-metal housing, and 6 rotary encoders. The Obokidlyamor Ferrari 296 GT box is the pick for users who want Sim Hub LED integration without paying premium prices.

Truck and farm sim players will get the most from the Logitech G Farm Sim Vehicle Side Panel, which is purpose-built for those genres with a 6-axis loader stick and 37 programmable buttons. The Quickcar Racing panels serve DIY builders who want real motorsport hardware integrated into custom sim cockpits.

Whichever best button boxes you choose from this guide, you will notice the difference the moment you adjust brake bias using a tactile encoder instead of fumbling for a keyboard shortcut. The investment pays off in immersion, lap time consistency, and long racing sessions where physical controls reduce finger fatigue.
