Abstract

Ein Niederspannungs-Leistungsschalter weist eine Kontaktanord­ nung mit schwenkbaren Hauptkontakthebeln (14) und eine relativ zu diesen schwenkbare Abbrennkontaktanordnung (22) auf. Die Abbrennkontaktanordnung (22) umfaßt Abbrennkontakt-Teilhebel (26) die zwischen die Hauptkontakthebel (14) eingreifen und gelenkig mit diesen verbunden sind. Ausgehend von dem hierdurch gegebenen Abstand sind die Abbrennkontakt-Teilhebel (26) an ihren vorderen Enden zur Bildung einer Auflagefläche für ein Abbrennkontaktstück (36) zusammengeführt und durch einen Niet (29) verbunden. Beim Abschalten werden die Abbrennkontaktstücke (36, 40) gegenüber den Hauptkontaktstücken (10, 12) verzögert geöffnet.
