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. In the preferred form, the driver also carries a cam mechanism that operates a spring contact that controls one circuit.
