Abstract

Ein Selbstschalter weist ein Schaltschloss auf, das mit lediglich einer einzigen Zugfeder auskommt, um sowohl die Anpresskraft als auch die Öffnungskraft zu erzeugen. Hierzu ist ein Steuerhebel vorhanden, der auf einer Achse gelagert ist, die gegenüber der Lagerungsachse für den Kontakthebel radial versetzt ist. Durch den seitlichen Versatz können Abstandsänderungen zwischen Teilen des Kontakthebels und Teilen des Steuerhebels dazu verwendet werden die notwendigen Schwenkbewegungen um die beiden Achsen zu erzeugen. Im Bereich der Feder ändert sich der relative Abstand zwischen den Verankerungspunkten der Feder an dem Steuerhebel und dem Kontakthebel.

Figure 00000001
A self-switch has a key switch that only needs a single tension spring to generate both the contact pressure and the opening force. For this purpose there is a control lever which is mounted on an axis which is radially offset from the bearing axis for the contact lever. Due to the lateral offset, changes in distance between parts of the contact lever and parts of the control lever can be used to generate the necessary pivoting movements around the two axes. In the area of the spring, the relative distance between the anchoring points of the spring on the control lever and the contact lever changes.
