Abstract

Verklinkungseinrichtung für einen elektrischen Schalter, insbesondere für einen Leitungsschutzschalter, mit einem Schalthebel (1), an dem schwenkbar ein Klinkenhebel (2) angelenkt ist, der mit dem am Kontakthebel (4) angeordneten Klinkenhebelwiderlager (3) ein Kniegelenk (2;3) bildet, durch das eine Übertotpunktlage bewirkt wird.
Das Klinkenhebelwiderlager (3) an dem der Kontaktstelle (4A) gegenüberliegenden Arm des Kontakthebels (4) ist so gestaltet und schwenkbar befestigt, daß es zwei unterschiedliche Entklinkungsabläufe zuläßt.

Figure 00000001
Latching device for an electrical switch, in particular for a circuit breaker, with a switching lever (1) on which a ratchet lever (2) is pivotably articulated, which forms a knee joint (2; 3) with the ratchet lever abutment (3) arranged on the contact lever (4) , which causes an overdead position.
The pawl lever abutment (3) on the arm of the contact lever (4) opposite the contact point (4A) is designed and pivotably attached so that it allows two different unlatching processes.
