Floor Mounting

Both

Pedal should be easily and rigidly mounted to a rigid floor panel

Travel Range

Both

Pedal should have a full angular range of travel of at least 20 degrees

You want a large operating range to work with, so you’re not working with micro

Mechanical Advantage

Both

The driver should be able to fully activate the mechanism with <=70lb of force

Ergonomics

Both

The driver’s foot should be able to easily/ergonomically apply force over the entire travel range of the pedal

Force resistance / springback

Both

The pedal should provide substantial resistance during operation (can be constant or linear)

Springback

Both

The pedal should return to its un-pressed position when force not applied

Angular Measurement

Accelerator (ideally brakes too)

The pedal shall measure its angular position and output the result to a controller board, with a measurement resolution of at least 0.5 degrees

Limit switch

Ideally both

The pedal should incorporate a limit switch that measures whether or not the pedal is depressed.

Ideally, the threshold for limit switch activation should be easy to adjust/tune
