What does a brake pedal switch do?

The brake pedal switch is a small device usually attached to the brake pedal mechanism. The brake pedal switch serves two major functions; it turns on the brake lights when a driver presses the brake pedal. It also sends a signal to your car’s computer that the brakes have been applied.
