Abstract

Elektrischer Schalter (1) mit zumindest einem Schaltkontakt (12a), der entgegen der Vorspannkraft einer Kontaktkraftfeder (13) an einem beweglichen Kontaktträger (11) gehalten ist, und mit einer Lichtbogen-Löscheinrichtung (2), bei dem sich zumindest ein Abschnitt (40) der zumindest einen Kontaktkraftfeder (13) zwischen seitlichen Wangen (38) des Kontakt - trägers (11) erstreckt, und bei dem ein Mittel zum Begrenzen der Ausbreitung von Abbrandprodukten (34) vorgesehen ist, das eine entgegen der Öffnungsrichtung (32) des beweglichen Kontaktträgers geneigte Abwinklung (37) aufweist, die bei geöffneter Stellung des Kontaktträgers den zumindest einen Abschnitt (40) der zumindest einen Kontaktkraftfeder (13) überragt.Electric switch (1) having at least one switching contact (12a), which is held against a counterforce of a contact force spring (13) on a movable contact carrier (11), and with an arc extinguishing device (2), wherein at least a portion (40 ) of the at least one contact force spring (13) between lateral cheeks (38) of the contact carrier (11) and in which a means for limiting the propagation of burned products (34) is provided, which is opposite to the opening direction (32) of the movable one Contact carrier inclined bend (37), which projects beyond the at least one portion (40) of the at least one contact force spring (13) in the open position of the contact carrier.

Um die Kontaktkraftfedern insbesondere am Ende des Öffnungsvorganges noch besser vor Verschmutzung durch sich ausbreitende Abbrandprodukte zu schützen ist vorgesehen, dass die geneigte Abwinklung (37) unter Vorspannung auf den seitlichen Wangen (38) aufsitzt.

Figure imgaf001
In order to protect the contact force springs even better, especially at the end of the opening process, against contamination by propagating burn-off products, provision is made for the inclined bend (37) to be prestressed on the lateral cheeks (38).
