Abstract

Die Erfindung betrifft eine Schaltkontaktanordnung insbesondere für einen Leistungsschalter, mit einer Doppelkontaktstelle pro Phase, mit zwei in Abstand zueinander angeordneten, in einer Phasenleitung befindlichen feststehenden Kontaktstücken, die von einer Kontaktbrücke überbrückt werden, mit je einer Kontaktdruckfeder und mit einer Kontaktbrückenführung für jede Phase. Die Kontaktbrückenführung ist durch einen Stößel (20, 20a, 20b) gebildet, der einen Fortsatz (24) mit einem Schlitz (25) aufweist, in den die zugehörige Kontaktbrücke (30) einlegbar ist, daß der die Kontaktbrücke (30) überragende Fortsatz (24) in eine Kontaktdruckfeder (34) einfügbar ist und daß der Stößel (20, 20a, 20b) mit der Kontaktbrücke in einer Aufnahmeöffnung des Leistungsschalters einrastbar ist.

Figure 00000001
The invention relates to a switching contact arrangement, in particular for a circuit breaker, with a double contact point per phase, with two spaced-apart, fixed contact pieces located in a phase line, which are bridged by a contact bridge, each with a contact pressure spring and with a contact bridge guide for each phase. The contact bridge guide is formed by a plunger (20, 20a, 20b) which has an extension (24) with a slot (25) into which the associated contact bridge (30) can be inserted, so that the extension (30) projecting beyond the contact bridge (30) 24) can be inserted into a contact pressure spring (34) and that the plunger (20, 20a, 20b) with the contact bridge can be snapped into a receiving opening of the circuit breaker.
