ABSTRACT:
A switch housing for an electric switch has a front end with a stop surface for contacting a front plate with a fastening element. Furthermore, the switch housing has on its rear a mounting surface parallel to the stop surface, to be fastened with the mounting surface on a printed circuit board. In this arrangement, the switch housing is assembled from two elements of which one switch element is brought into connection with the front plate, and for the other switch element is connected to the printed circuit board. One of the two elements has a clip which connects with a locking pin arranged in the other one of the two elements or capable of being pushed forward, with the result that the two switch elements of the switch housing make effective functional contact with one another. This renders it possible for a printed circuit board provided with the first preassembled elements of the switch housings to be assembled durably and yet detachably with a front plate provided with the other preassembled elements of the switch housings, without the need to provide additional spacing elements.
