    摘要: An electrical switch having a contact carrier plunger which is rectilinearly guided in a housing and which can be driven by rotatable cam rollers which are arranged to be rotated on a shaft by an actuating member inserted through an opening in the switch housing. The arrangement is configured so that the roller rotation will be locked when an actuating member differing from a prescribed predesigned shape is attempted to be used. When an actuating member of the predetermined shape is employed, however, the two rollers can be laterally displaced from one another along their axis of rotation to unlock the plunger movement as the actuating member is forced against mating surfaces performed on the rollers. The openings through which the actuating member may be inserted each consists of two slots separated by an intermediate wall. The actuating member has a slot corresponding to the thickness of the intermediate wall to enable actuation of the switch only if an actuating member of a predetermined shape configuration is inserted in the slots.
