ABSTRACT:
An electrical switch operated by the input member of a hydraulic master cylinder and controlling the stop signal lights of a motor vehicle, when associated with the master cylinder of a hydraulic brake system, and/or controlling a cruise control disconnect circuit. When associated with the master cylinder of a clutch hydraulic control system, the switch is adapted to close an interlock circuit allowing the motor vehicle driver to start the engine only when the clutch is fully released, and to operate a cruise control disconnect circuit upon small displacement of the input member from its home position.
