Brake Switch (Cruise Control): Description and Operation






If the brake pedal is depressed rapidly while the speed control system is active, the speed control servo receives a input from the deactivator switch. This causes, the electromagnetic actuated coupling to disconnect from the stepper motor and deactivate. This allows the cable and throttle to close under throttle return spring control. The system is put in stand by mode.
