Momentary Switches
Unlike standard latching switches, ours spring back after every input - so they behave like a button press and can be assigned reliably in your sim.

Our 150 g encoders were deliberately chosen for stronger resistance based on customer feedback. Their defined tactile steps let you feel every adjustment – even with gloves – and help prevent accidental over-adjustment

Brake bias at your fingertips More info
Brake bias at your fingertips
Shaped after a real brake-bias control, the larger diameter makes fine adjustments quick and precise. Easy to find with gloves and with clear tactile feedback at every step.

Over 5000 SimRacers Drive with BoxOneRacing
Real rigs. Real racers. Real results.

Your sim racing is in good hands
Hi, I’m Luis, founder of BoxOneRacing.
I’m a sim racer myself.
BoxOneRacing is built from real racing experience.
I started developing my own Button Boxes because everything on the market felt like a compromise.
High prices. Missing functions. Cheap switches. Weak mounting.
So I built what I couldn’t find.
No mass production. No compromises.
From sim racers. For sim racers.

Try it for 60 days on your own setup
Use it in real races, feel the buttons and encoders, and see if it truly fits your rig.
If it isn’t right for you, you can return it within 60 days under our Test Drive Guarantee.
