Brake Switch (Cruise Control): Description and Operation
Deactivator Switch
The deactivator switch:
-
Is a normally closed switch. Replaces the speed control dump valve as a redundant safety feature in the system.
-
Uses an electrical signal from the stoplight switch circuit to the speed control servo to disengage the system when the brake pedal is applied.
-
Under increased brake pedal efforts (22.25-44.5 N [15-10 Lbs]), engine running), the deactivator switch mounted in the brake line will open and
remove power to the speed control servo, releasing the throttle from speed control servo control.
-
Is located at the rear brake pressure control valve (anti-lock brakes) or brake pressure switch adapter (conventional hydraulic brakes) below the
power brake booster.
-
Is mounted to end part of the brake pressure control valve. The brake pressure control value is mounted in-line to the rear brake hydraulic lines.
