Brake Pressure Applied Switch





Brake Pressure Applied Switch


Brake Pressure Applied Switch:






NOTE: The Brake Pressure Applied Switch is present on vehicles equipped with speed control.

All vehicles have a single Brake Pressure Applied (BPA) switch. A BPA switch provides a backup for the Brake Pedal Position (BPP) switch. Normally, a brakes-applied signal from the BPP switch will disengage the speed control. If the BPP switch signal is lost, the BPA switch will then supply the brakes-applied signal to the speed control system.
