Brake Switch Description

WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.

The brake switch is a push-type installed in the upper part on the brake pedal, and detects brake pedal application.
When the brake pedal is depressed during TCC, the PCM releases TCC operation for smooth deceleration.

See Figure.
