ABSTRACT:
An electric switch is provided with a support frame at which several key switch elements are individually clipped on. An actuating front piece is attached at the support frame, which is mounted at a front plate of a switching cabinet or the like. A transmission apparatus with a compression spring is provided between a pressure pin of the actuating front piece and a ram of the key switching elements. The compression spring, the ram and the pressure pin are disposed in an inner space of the support frame receiving the key switching elements. The transmission apparatus provides several individual thrust journals which are resting in the base body and which are moved against the force of the individually coordinated overthrow springs for actuating the key switch elements against the ram.
