Abstract: A tool for use in removing and replacing a bulb of a push-button type actuatable switch comprises a tool body having a first end defining a bulb-accepting opening. A plurality of tines surround at least a portion of the opening. When the tines are in a first position, the opening is sufficiently large to accept a bulb. When pressed inwardly, the tines reduce the size of the opening and engage a bulb located therein. Movement of a sleeve over the outside of the body presses the tines inwardly. In one embodiment, a flexible sleeve is located in the opening for gripping and protecting a bulb. A stop extends into the insert, limiting the extent to which a bulb may be pressed into the tool. An opposing end of the tool may include a prong or blade for engaging and removing a lens cover over a bulb.

Abstract: The housing for an electric snap action switch has a front section with a frame having a surface serving to abut the front side of a mounting plate, and a coaxial rear section with a surface facing away from the surface of the frame and serving to abut or to be placed adjacent one side of a circuit board. A nut mates with an externally threaded tubular portion of the front section to maintain the surface of the frame in abutment with the mounting plate. The two sections are separably coupled to each other by resilient male detent elements which are provided on the front section and extend into complementary female detent elements of the rear section. The housing acts as a distancing element between the mounting plate and the circuit board, and its rear section has a recess for a switching unit which is secured to the circuit board and can be actuated by movable parts which are installed in the front section. The rear section is secured to the circuit board by screws.
