Abstract

Bei einem Tastschalter mit einer Blattfeder mit ge­ schlitzten Blattenden für einen Doppelkontakt mit einem quer dazu angeordneten Festkontakt sind die Federenden in Richtung der Blattfederachse mit einer rillenförmigen Einprägung versehen. Dadurch ergibt sich ein punktför­ miger Kontakt, der infolge Durchbiegung der Blattfeder wandert, so daß sich ein hoher Kontaktdruck und eine Selbstreinigung der Kontakte ergibt.
