Abstract

A pushbutton contactor has means for transforming the contacting function into a locking function or vice versa in which detent means are provided on the actuating member which cooperate with cam surfaces in the guide cylinder of the pushbutton contactor. Different cam surfaces in a guide cylinder are offset from each other and can be brought into operative connection with the detent means. By simple displacement of the actuating member, the function of the pushbutton contact can be changed from a locking to an intermittent contact or vice versa.
