Abstract

Das Tastenfeld hat auf einer Grundplatte (1) mit Leiter­ bahnen (8, 9) Schaltkontakte (2, 3), die elektrisch mit den Leiterbahnen verbunden sind. Eine Schaltfolie (5) besitzt gegenüberiiegend und den Schaltkontakten zugewandt eine Kontaktfläche (6), welche bei mechanischer Durchbiegung der Schaltfolie die zugeordneten Schaltkontakte (2, 3) elek­ trisch miteinander verbindet. Eine Zwischenisolationsschicht (4) dient als Abstandhalter für die Schaltfolie (5) und trennt somit auch die Kontaktfläche (6) von den Schaltkontakten (2, 3). Im Bereich der Schaltkontakte weist diese Zwischeniso­ lationsschicht (4) Ausnehmungen (10) auf. Die Zwischeniso­ lationsschicht (4) ist auf die Grundplatte aufgetragen, vor­ zugsweise mittels Siebdrucktechnik.
