Abstract

Bei einem Drucktaster (1) ist zwischen einem Gehäuse­ unterteil (2) und einem entgegen der Kraft einer Druckfeder (10) verschiebbaren Druckstück (6) eine Bügelfeder (21) eingesetzt, die geneigt zu dessen Verstellrichtung (A) ange­ ordnet und um die Abstützung an dem Gehäuseunterteil (2) verschwenkbar ist. Auf diese Weise wird, da die mit zu überwindende Kraft der Bügelfeder (21) bis zu deren achssenkrechten Totpunktlage überproportional ansteigt und danach stark abfällt, ein Druckpunkt geschaffen, so daß der Bereich des Drucktasters (1), in dem eine Schaltung erfolgt, exakt definiert ist. With a push button (1) is between a housing lower part (2) and one against the force of a compression spring (10) displaceable pressure piece (6) a bow spring (21) used, inclined to the direction of adjustment (A) arranges and around the support on the lower housing part (2) is pivotable. In this way, since that too overcoming force of the bow spring (21) up to its Dead center position increases disproportionately and then drops sharply, creating a pressure point so that the area of the push button (1) in which a circuit is exactly defined.
