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. With a push button switch with a leaf spring with ge slotted blade ends for double contact with one The spring ends are arranged perpendicular to it in the direction of the leaf spring axis with a groove-shaped Provide embossing. This results in a point moderate contact due to the deflection of the leaf spring migrates so that there is a high contact pressure and a Self-cleaning of the contacts results.
