Abstract
Elektromagnetisches Schaltelement, insbesondere ein Schütz, mit einer Spule (14), einem ortsfesten Joch (9) sowie einem Anker (8), der Schaltkontakte (16) trägt und zwischen einer ersten Schaltstellung, in der er vom Joch (9) beabstandet ist und einer zweiten Schaltstellung, in der er in unmittelbarer Nähe zum Joch (9) liegt, beweglich gehalten ist, und die Schaltkontakte (16) des Ankers (8) in diesen beiden Schaltstellungen mit ortsfesten Schaltkontakten (15) zusammenwirken, um unterschiedliche Schaltzustände zu verwirklichen, wobei der Anker (8) und das Joch (9) einander zugewandte Flächenabschnitte (10, 11, 12, 13) aufweisen, die sich in der zweiten Schaltstellung berühren oder annähernd berühren. Erfindungsgemäß ist vorgesehen, dass zumindest einer dieser Flächenabschnitte (10) des Ankers (8) und der ihm zugewandte Flächenabschnitt (11) des Jochs (9) eine unterschiedliche Krümmung aufweisen. Electromagnetic switching element, in particular a contactor, with a coil (14), a stationary yoke (9) and an armature (8), the switching contacts (16) carries and between a first switching position in which it is spaced from the yoke (9) and a second switching position in which it is in the immediate vicinity of the yoke (9), is movably held, and the switching contacts (16) of the armature (8) in these two switch positions with stationary switch contacts (15) cooperate to realize different switching states, wherein the armature (8) and the yoke (9) have facing surface portions (10, 11, 12, 13) which touch or touch in the second switching position. According to the invention, at least one of these surface sections (10) of the armature (8) and the surface section (11) of the yoke (9) facing it have a different curvature.
