Brake Light Switch
The brake light switch on the pedal turns on the brake lights and tells control units when the brake is pressed.
What is Brake Light Switch?
It is used by cruise control, shift lock and stability control. Many have two contacts for safety. It must be adjusted correctly. Some switches are adjusted by pulling the plunger out fully and letting the pedal set the position. On many modern cars a brake pedal position sensor replaces the simple switch.
How it works
Pedal movement opens or closes its contacts.
Why it matters for your car
A faulty switch can cause brake lights to stay on or not work. It can also stop cruise control or the gear selector from working.
