Abstract

Bei einem Tastschalter ist ein Träger (1) mit darauf angeordneten Leiterzügen (3) und Schaltkontaktflächen (2) vorgesehen. Um hiermit neben einfachen Ein-Aus-Schalt­ vorgängen in einer Einheit auch Zusatzfunktionen ausüben zu können, sind auf dem Träger (1) Schaltelemente (4, 5 ,6) angeordnet, die Entkopplungsdioden, Entprellschaltungs­ einrichtungen, Mikroprozessoren, Anzeigeelemente od.dgl. enthalten. Diese Schaltelemente sind als Filmschaltelemen­ te ausgebildet und mit Leiterzügen des Trägers (1) verbun­ den. In the case of a pushbutton switch, there is a carrier (1) on it arranged conductor tracks (3) and switching contact surfaces (2) intended. In addition to simple on-off switching also perform additional functions in one unit switching elements (4, 5, 6) on the carrier (1) arranged, the decoupling diodes, debouncing circuit facilities, microprocessors, display elements or the like. contain. These switching elements are called film switching elements te trained and connected with conductor tracks of the carrier (1) the.
