Abstract
A switching device having an open-ended hollow cylindrical housing with a number of slots in the sidewall. An insulative piston is slidably movable along the housing longitudinal axis and has a threaded central opening receiving a similarly threaded axle. A receptacle switch part fits onto a housing end and includes a central opening through which an unthreaded portion of the axle extends. Openings in the receptacle switch part each have a sleeve contact with outwardly extending tabs for electrical connection to cable wires, or the like. The piston has a plurality of pin contacts fixedly mounted thereto with portions extending from both sides of the piston for electrical connection to cable wires, for example, and which respectively align with a sleeve contact in the switch part. A further receptacle switch part is affixed to the housing other end. Rotative power drives the piston along the housing to effect connection between the contacts.
