Abstract

Die vorliegende Erfindung bezieht sich auf ein bistabiles Schütz mit wenigstens einer Spule (7,8) und einem gegenüber der Spule beweglichen Anker (23) mit Kontakten (22), der zusammen mit den Kontakten zum Öffnen oder Schließen eines Stromkreises mittels der Spule von einer ersten stabilen Stellung in eine zweite stabile Stellung überführbar ist, und einem Dauermagneten (17), über den sich der Anker in einer seiner stabilen Stellungen gegenüber der Spule abstützt, wobei der Dauermagnet gegenüber der Spule ortsfest ist und ein Federelement (28) vorgesehen ist, das den Anker in die andere stabile Stellung vom Dauermagneten beabstandend vorspannt.

Figure 00000001
The present invention relates to a bistable contactor with at least one coil (7, 8) and an armature (23) with contacts (22) which is movable with respect to the coil and which together with the contacts for opening or closing a circuit by means of the coil of one first stable position can be converted into a second stable position, and a permanent magnet (17), via which the armature is supported in one of its stable positions with respect to the coil, the permanent magnet being stationary with respect to the coil and a spring element (28) being provided, that biases the armature into the other stable position spaced from the permanent magnet.
