Abstract: The inventions solves the problem of convenient mounting of parts of controllers, and solves the problem of interchangeability of vacuum and air break contactors within a controller. A controller has a housing, an isolation switch mounted within the housing, a contactor mounted within the housing and connected electrically downstream from the isolation switch, and the controller has a receptacle which can accept either a vacuum contactor or an air break contactor. Also, the contactor has an operating coil and control components mounted on a side facing a door of the housing so that the coil can be replaced and the control components serviced without disturbing the contactor.

Abstract: An electric switch has a first molding for supporting an isolation switch and at least one line side power fuse clip, where the line fuse clip is capable of retaining a first end of a power fuse fed by the isolation switch. A second molding for supporting at least one load side power fuse clip is provided, where the load fuse clip is capable of retaining a second end of the power fuse. At least one projection is formed into the second molding for supporting a control circuit fuse, where the projection is substantially parallel to and beside an installed power fuse, and a control circuit line side fuse clip and a corresponding load side clip is mounted to each of the projections formed into the second molding, so that installed control and power fuses are spaced apart and substantially parallel. A conductor behind a terminal of the power fuse connects the load side power fuse clip to the control circuit line side fuse clip.

Abstract: A circuit breaker operating apparatus is of the type having an enclosure, the circuit breaker mounted inside the enclosure, the circuit breaker has an operating toggle, the operating toggle has at least a trip position into which trip position the toggle is urged when the circuit breaker goes into a trip condition, the apparatus has a handle mounted on the exterior of the enclosure, the handle has a lever mounted for rotational motion relative to the enclosure. A guide is fixedly attached to the handle; a cam link, the cam link having a first end rotatably attached to the lever, and the cam link having a second end slidably attached to the guide so that as the lever undergoes rotation the second end of the cam link moves along the guide.
