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.
