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.
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.
