Abstract: A vehicular switch for activating and deactivating a circuit or circuits in response to movement of one vehicular component relative to another such as a door relative to a door frame. The switch is a compact miniaturized unit insertable in the fixed component and self-adjusting to accommodate variations in spacing between fixed and movable components. Seals are provided to block access of water or other destructive materials irrespective of the position of the movable vehicle component relative to the fixed component. All electrical elements are completely enclosed in a weather-tight package.

Abstract: A switching system operable in response to the travel of a vehicular lever or pedal such as a clutch for opening and closing operating circuits of the vehicle. The system includes actuators for moving switch contacts to change the conditions of the circuits in which they are incorporated and extension arms connected to said actuators through ratchet-and-pawl mechanisms. The extension arms are contacted and moved by an arm of the vehicular lever or pedal against spring bias which returns the actuators to the positions they were in before contact by the pedal arm. The ratchet-and-pawl mechanisms automatically compensate for increases in travel and may be reset for decreases in travel of the lever or pedal.

Abstract: A multi-function actuator switch attaches onto an actuator of already assembled clutch assembly or the like with a simple sideways snap-fit, is fully enclosed when assembled onto the shaft, and is compact. The switch has a hollow housing with a longitudinal opening. The housing carries in its interior a driver member that snap-fits onto the shaft. A pair of coil springs held on guide arms urge the driver toward an initial position. The arms are mounted on a base plate that closes one end of the housing and also snap-fits on the shaft. A replaceable cover closes the longitudinal opening in the housing and locks the housing onto the shaft. The housing mounts a terminal board that carries a molded in place set of interior contacts that each connect with a terminal at the exterior of the housing. The driver carries a wiper contact that makes electrical connections between selected pairs of contacts as a function of its position in the switch to control the operation of circuits associated with those contacts.

Abstract: A thermally actuated switch including a motive member which is adapted to move one contact either toward or away from its opposed mating contact in response to an increase or decrease in pressure in a fluid actuating heat sensing system, the fluid system translating temperature into fluid pressure. The assembly further includes a hydraulically actuated high temperature switch which is adapted to be rendered responsive to a preselected temperature, as for example, 550.degree. to 600.degree., the switch being utilized to control an external circuit, as for example, the deactivation of a door lock solenoid. The switch assembly includes two fixed contacts, the positions of which are fixed in response to the position of a cam element. A pair of mating movable contacts are controlled by a temperature responsive assembly, which temperature responsive assembly reacts in response to the sensed temperature of an oven.
