Abstract
A multipolar rotary switch, in particular a cam switch, is constituted by a stack of wafers with the contact elements and the connection elements being received in chambers lying between end walls and intermediate walls. The end walls and the intermediate walls are provided in the form of molded parts (16) of thermoplastic material and these parts are mechanically assembled to one another and are rigidly fixed together. The molded parts (16) have lugs (50) which, during assembly, overlap the sides of the adjacent molded parts and latch behind projections (62) provided thereon. After latching, the lugs (50) are welded to the side walls of the molded parts (16) in order to provide an assembly which is rigid.
