Abstract

Der Tastenschalter besteht aus einem Kontaktträger (1), einer mit Öffnungen (4) für die Schaltkontakte (2, 18) versehenen Abstandsfolie (3) einer Wölbungen mit Schalt­ kontakten (18) aufweisenden und auf der Abstandsfolie (3) aufliegenden Schaltkontaktfolie (5) und einer auf der Schalt­ kontaktfolie aufliegenden Abdeckfolie (9). Die Wölbungen der Schaltkontaktfolie weisen mindestens drei durch Frei­ stanzungen erzeugte, sternförmig verlaufende Stege auf, von denen der das Leitermaterial (17) tragende Steg (6) breiter ist als die den Steg (6) abstützenden übrigen Stege. Die Schaltkontaktfolie (5) wird aus Isoliermaterial hergestellt, auf das die Leiterschicht (17) aufgedruckt, aufgedampft oder sonstwie aufgebracht ist. The key switch consists of a contact carrier (1), one with openings (4) for the switch contacts (2, 18) provided spacer film (3) of a bulge with switching contacts (18) and on the spacer film (3) switch contact foil (5) and one on the switch contact foil cover foil (9). The bulges the switch contact foil have at least three by clear punched-out, star-shaped webs, of which the web (6) carrying the conductor material (17) is wider than the other webs supporting the web (6). The switch contact foil (5) is made of insulating material, on which the conductor layer (17) is printed, evaporated or otherwise is upset.
