Abstract

Ein Folientastschalter weist eine Basisfolie 1, eine Oberfolie 2 und eine Schaltkammern 4 bildende Abstands­ folie 3 auf. Um bei einer Tastenbetätigung gleichzeitig zwei Schaltkreise ohne zusätzlichen Hub schließen zu können, verlaufen in einem zentralen Bereich der Schalt­ kammer 4 Leiterendstreifen 6 bis 11 von zwei Schalt­ kreisen so parallel nebeneinander, daß die Gesamtbreite der Parallelanordnung wesentlich kleiner als der Durch­ messer der Schaltkammer 4 ist. Außerdem sind zwei Kontaktflächen 14, 15 vorgesehen, die jeweils nur die Leiterendstreifen eines der Schaltkreise überdecken. A membrane switch has a base film 1, a Upper film 2 and a switching chambers 4 forming distance slide 3. To at the same time when a key is pressed two circuits close without additional stroke can run in a central area of the switching chamber 4 conductor strips 6 to 11 of two switching circle in parallel so that the total width the parallel arrangement much smaller than the through knife of the switching chamber 4. There are also two Contact surfaces 14, 15 are provided, each only the Cover the conductor end strips of one of the circuits.
