Abstract

Die Erfindung bezieht sich auf eine Tastschaltvorrichtung mit mehreren zu einem Tastenfeld gruppierten Tastschaltern, die mit ihren Betätigungselementen (1, 2) auf eine Hubbälge aufweisende, elastische Eigenschaften aufweisende Matte (6) einwirkt. Jeder Hubbalg trägt in seinem Inneren ein Kontakt­ stück (7, 8), das bei niedergedrückter Taste auf einer Isolier­ platte angeordnete Kontaktstellen (11, 12) schnappartig über­ brückt. Aufgabe der Erfindung ist es, die Anzahl der Schalt­ kreise zu erhöhen. Dies wird dadurch erreicht, daß unterhalb der Kontaktmatte (6) zwei mit Leiterbahnen und Kontaktstellen versehene Kontaktfolien (9, 10) angeordnet sind, daß die bei­ den Kontaktfolien durch eine Zwischenlage (17) aus Isolier­ stoff voneinander getrennt sind, daß im Bereich der Kontakt­ stellen die Zwischenlage mit Ausnehmungen versehen ist und daß die obere Kontaktfolie (9) auf beiden Seiten mit Leiterbah­ nen und Kontaktstellen versehen ist, während die darunter lie­ gende Kontaktfolie (10) nur einseitig mit Kontaktstellen (15, 16) versehen ist. Anwendbar bei Tastaturen der Fernsprech­ technik.
