Abstract

Die Erfindung betrifft ein elektromagnetisches Schaltgerät mit einem Magnetsystem mit Joch und Anker, dessen Anker mit einem im Gehäuse des Schaltgerätes geführten Kontaktträger quer zur Betätigungsrichtung nebeneinanderliegende Schalt­ kontaktteile aufweist, die mit feststehenden Kontaktteilen Schließer- bzw. Öffnerkontakte bilden und in dem Abstützungs- bzw. Mitnahmeanschläge für die Schaltkontaktteile vorgese­ hen sind.
Die Kontaktträger sind im Gehäuse mit Spiel geführt, so daß ein Kippen möglich ist. Im Hinblick auf diese Kippbe­ wegung muß der Freiweg, das ist der Weg, der vom Abheben aller Öffnerkontakte bis zum Anlegen aller Schließerkon­ takte notwendig ist, auf den zuletzt abhebenden Öffnerkon­ takt abgestellt werden.
Um diesen Freiweg relativ groß zu halten, werden die der Gehäusewandung zugewandten Anschläge gegenüber den mittle­ ren Anschlägen in Bewegungsrichtung voreilend angeordnet, so daß der durch das Kippen verlorene Freiweg dadurch wie­ der gewonnen wird. Somit kann der Kraftbedarf gegenüber der üblichen Ausführung niedriger gehalten werden kann, da sie sich günstig auf die Zugkraftkurve auswirkt.
