Stop Lamp Switch
WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
The stop lamp switch is installed to the brake pedal bracket. The switch detects state of the brake pedal and transmits an ON/OFF signal to VCM.
The contact of the stop lamp switch is usually open. When the brake pedal is depressed, it closes and the stop lamp switch signal is transmitted as a voltage signal.
