Brake Light Switch: Description and Operation
Brake Lamp Switch Circuit
BRAKE LAMP SWITCH CIRCUIT
This switch prepares the CAB for a possible antilock stop. The antilock system uses an input signal from the brake pedal switch when activated. A
released brake pedal will close the switch circuit and read O volts. When the driver applies the brake pedal, the circuit voltage is 12 volts. This signal
tells the CAB that the pedal is depressed. The brake lamp switch is located on the brake pedal under the driver dash.
