The housing parts interfit to form a generally rectangular parallelepipedal structure provided at one end with a threaded connection for a threaded connector, pipe or conduit through which conductors may be passed to connect to the electronic device within the housing. The bottom housing portion is provided with the connecting circuitry while the top housing portion, interfitting with the bottom housing portion, has a part overhanging the latter and provided with the plug connectors forming a detachable electrical connection with the connecting circuitry permanently received in the lower housing portion. The upper housing portion contains all of the switch circuitry in its receptacle.
