A pushbutton has an actuating part 2 which can move in an outer part 3'. It is provided with an internal pin 2a', 2a", 2a'", which depending on how the actuating part 2 is operated can interact with contact devices 8', 8" belonging to the pushbutton. The pushbutton pattern and/or mounting cards are arranged one on top of the other with a first intervening space, which carry contact elements, that can interact with the contact device. Furthermore, a separate force-transmitting unit is mounted in a recess in the upper of the mentioned cards. A first contact device extends between said pin and the force-transmitting unit in a second space above the upper card of said cards so that the actuating of the unit from said pin during movement of the actuating part occurs via the first contact device. The latter in this process supports the pieces of the first contact device that can interact with corresponding first contact elements on at least the top of the upper card. Said unit can also interact with a second contact device placed in said first space between the cards, which supports pieces of the second contact device, which can interact with the second contact element at the bottom of the upper card and/or the top of the lower card. <IMAGE> |
