Abstract

Die bewegliche Elektrode der Schalteinrichtung besteht aus einem flexiblen, zusammendrückbaren Kontaktgewebe (1) mit leitenden und nichtleitenden Drähten (2, 3). Die leitenden Drähte (2) erstrecken sich in der einen Webrichtung und verlaufen wenigstens annähernd in einer Ebene. Demgegenüber sind die in der anderen Webrichtung sich erstreckenden nichtleitenden Drähte (3) um die leitenden Drähte (2) gebogen, so dass sie die leitenden Drähte (2) im Abstand zu einer am Kontaktgewebe (1) anliegenden Flachelektrode (4) halten. Durch Zusammendrücken des Kontaktgewebes (1) werden die leitenden Drähte (2) biegeelastisch verformt, wobei die an diesen entstehenden Wellenrücken an die Gewebeoberfläche gelangen und dadurch mit der Flachelektrode (4) in Kontakt kommen.
Eine derartige Schalteinrichtung zeichnet sich durch einen einfachen Aufbau und eine geringe Bauhöhe aus.
