Abstract

Ein elektromagnetischer Schal terantrieb mit einem von einer Magnetspule (10) umgebenen Magnetkern (11) und einem mit dem Magnet­ kern fest verbundenen, winkeligen Magnetjoch (12) wirkt mit einem Klappanker (13) zusammen und zeichnet sich dadurch aus, daß die Auflagerung des Klappankers auf der Polfläche (14) des Magnetjochs in einer Winkelnische gelegen ist, die aus dieser Polfläche und einer angren­ zenden Wandungsfläche (23) gebildet ist, daß der Klap­ panker sich über die Polfläche (15) des Magnetkernes (11) hinweg bis hin zu einem beweglichen Kontaktträger (20) ertstreckt und mit diesem in kraftschlüssiger Ver­ bindung steht, daß der Klappanker von dem beweglichen Kontaktträger in seine Öffnungsstellung geführt und hierin gehalten wird, und daß der Klappanker in seiner Öffnungsstellung in einem Längsbereich zwischen seiner Lagerstelle und seiner Verbindungsstelle mit dem Kon­ taktträger an einer eine Hebelgelenkstelle bildenden Anschlagkante (40) anliegt und hieran durch die Kraft der Rückstellfeder des Kontaktträgers angedrückt wird, wodurch die Lagerschneide des Klappankers in kraft­ schlüssiger Anlage an der Polfläche des Magnetjochs ge­ halten ist. Ein solcher Schalterantrieb weist eine ge­ ringe Anzahl von Montageteilen auf und ist einfach zu montieren. An electromagnetic scarf drive with a magnetic coil (10) surrounded by a magnetic core (11) and a fixed to the magnetic core, angled magnetic yoke (12) interacts with a hinged armature (13) and is characterized in that the support of the hinged armature is located on the pole face (14) of the magnetic yoke in an angular recess, which is formed from this pole face and an adjoining wall surface (23) that the Klap panker over the pole face (15) of the magnetic core (11) up to one Movable contact carrier (20) extends and with this in a non-positive connection that the hinged anchor is guided by the movable contact carrier in its open position and held therein, and that the hinged anchor in its open position in a longitudinal region between its bearing point and its connection point with the Kon tact bearer rests against a stop edge (40) forming a lever joint point and against it by the force of the Return spring of the contact carrier is pressed, whereby the bearing edge of the hinged armature is held in a force-fitting manner against the pole face of the magnetic yoke. Such a switch drive has a small number of assembly parts and is easy to assemble.
