ABSTRACT:
An electrical switch for sensing operation of a hydraulic cylinder, the switch being normally open and closing an electrical circuit when the cylinder is pressurized to effect a desired operation only when there is fluid at a predetermined pressure in the cylinder. The hydraulic cylinder is the slave cylinder of a motor vehicle clutch hydraulic control and the electrical circuit controlled by the switch is, for example, the motor vehicle engine starter motor relay circuit, such that the starter relay circuit is inhibited unless sufficient pressure is present in the cylinder, corresponding to the pressure necessary to cause the slave cylinder output member to fully release the clutch.
