Brake Light Switch: Description and Operation
STOP LAMP SWITCH DESCRIPTION
The stop lamp switch is located under the instrument panel directly above the brake pedal. Whenever the brake pedal is pressed, one set of stop lamp
switch contacts close and a voltage signal is provided to the cruise control module. The cruise control module disengages cruise control system operation
as soon as this voltage signal is sensed.
When the brake pedal is pressed, another set of stop lamp switch contacts open, and the voltage circuit from the cruise control module to the magnetic
clutch inside the servo is interrupted. With voltage removed from the magnetic clutch, the servos DC servo motor is disengaged from the worm gear and
the throttle is permitted to return to the idle position. This feature is provided to ensure the cancellation of cruise control system operation during vehicle
braking. For stop lamp switch replacement and adjustment procedures, refer to Stop Lamp Switch Replacement in Lighting Systems.
