ABSTRACT:
In a switch arrangement for switching electrical functions with at least two switches (A;B) having electrical contact elements (8;9;10;11), at least one of the switches (A;B) is made as a foil switch having a flexible base foil (4;7) carrying one contact element (9;11) and a switch element (2;5), particularly a switch foil, elastically deflectable in the direction toward the base foil and carrying the opposite contact element (8;10). The other switch (B) is so arranged behind the foil switch (A) in the keying direction that it is operable by an operating pressure on the foil switch (A) which exceeds the required operating pressure for the foil switch (A).
