Abstract

Die Erfindung betrifft ein Leistungsschalter für hohe Ströme und Niederspannung, der ein Unterteil (2) mit Zwischenwänden (5), einen in Seitenblenden (28) gelagerten Betätigungsmechanismus (30) mit einem Kniehebelsystem (34) aufweist und mehrere Kontakteinheiten (9 ... 11) aufweist. Die Kontakteinheiten (9 ... 11) enthalten mehrere bewegliche Kontaktfingern (18), die in einem U-förmigen Kontakthalter (24) gegen die Wirkung von Kontaktdruckfedern (26) schwenkbar gelagert sind. Ein Verbindungssteg (38) aus isolierendem Formstoff ist einstückig mit den Kontakthaltern (24) verbunden und verläuft oberhalb der Kontaktdruckfedern (26). Die mittlere Kontakteinheit (10) ist über ein in den Seitenblenden (28) schwenkbar gelagertes Halteblech (42) gelenkig mit dem Kniehebelsystem (34) gekoppelt. An dem Verbindungssteg (38) sind Abschirmsegmente (56, 57) angeformt, die an den Zwischenwänden (5) im Bereich von Aussparungen (54) verlaufen, die für die Schaltbewegung des Verbindungssteges (38) vorgesehen sind.
