Abstract (en)
[origin: EP0235517A2] A layered push button switch has a base layer 1, an upper layer 2 and a spacer layer 3 forming a switch chamber 4. In order to be able to close two circuits simultaneously with one key operation, without any additional movement, conductor end strips 6 to 11, of two circuits, run parallel to one another in a central region of the switch chamber 4 such that the overall width of the parallel arrangement is significantly less than the diameter of the switch chamber 4. In addition, two contact surfaces 14, 15 are provided which in each case cover only the conductor end strips of one of the circuits. <IMAGE>
