Brake Light Switch: Description and Operation
Description
DESCRIPTION
The brake lamp switch is a two circuit, spring-loaded plunger actuated switch that is secured to the brake pedal support bracket under the instrument
panel on the driver side of the vehicle. The molded plastic switch housing has an integral connector receptacle containing four terminal pins. The switch
is connected to the vehicle electrical system through a dedicated take out of the vehicle wire harness.
The switch plunger extends through a mounting collar on one end of the switch housing. The plunger has a telescoping self-adjustment feature that is
activated after the switch is installed by the brake pedal as it moves upward to its normal at-rest position. The telescoping plunger can be pulled outward
from the switch housing to repeat the self-adjustment procedure if necessary.
The brake lamp switch cannot be repaired. If the switch is damaged or ineffective it must be replaced with a new unit.
