Brake Switch (Cruise Control): Description and Operation

DESCRIPTION
The Brake Pressure Switch acts as an additional speed control deactivation device should the brake switch fail.

OPERATION
Depressing the brake pedal with an additional pressure creating 125 psi in the brake line, causes the brake pressure switch to open, thereby removing voltage and current from the electric clutch within the speed control servo.
