ABSTRACT:
A self contained switch assembly of the type indicating the status of a moveable mechanical structure, such as a door being in proper position for latching, includes a proximity sensor mounted to a base plate. Also mounted to the base plate is a plunger mechanism which carries a target plate. Upon the striker surface of the plunger engaging an external object, the target plate moves into proximity with the sensor, thereby producing a status signal.
