[origin: EP1460666A2] The pushbutton two mechanically decoupled switching elements (2,3) which are operated in common by an actuator (10). The first switching element (2) interrupts a normally closed signal path (40), and closes a normally open signal path (41) when the pushbutton is operated. The second switching element is connected in the normally open signal path and closes the signal path when the pushbutton is operated.
