Abstract

Die Erfindung bezieht sich auf ein für eine Tastatur geeignetes Tastenglied. Um ein solches Tastenglied leich­ ter herstellbar und austauschbar auszubilden, sind folgen­ de Merkmale vorgesehen: ein Gelenk 14, 15; ein bezüglich des Gelenks 14, 15 nach einer Richtung hin abstehender und mit dem Gelenk verbundener Tastenvorsprung 12; ein be­ züglich des Gelenks 14, 15 nach einer anderen Richtung hin abstehender und mit dem Gelenk verbundener Stößer 16 und eine Feder 17, die derart angeordnet ist, daß sie sich verbiegt, wenn der Tastenvorsprung 12 um die Achse 23 des Gelenks 14, 15 schwenkend nach unten gedrückt ist, und hierdurch diesem nach unten erfolgenden Drücken einen Widerstand entgegensetzt. The invention relates to a keyboard suitable key link. To make such a key link easy Training to be produced and exchangeable follows de features provided: a hinge 14, 15; a re of the joint 14, 15 protruding in one direction and key projection 12 connected to the joint; a be with respect to the joint 14, 15 in a different direction protruding pusher 16 connected to the joint and a spring 17 which is arranged so that they bends when the key projection 12 about the axis 23 of the Joint 14, 15 is pivotally pressed down, and thereby this one pressing down Opposed resistance.
