Abstract

Die Erfindung betrifft ein elektromagnetisches Schaltgerät mit in einem mehrteiligen Gehäuse angeordneten beweglichen Schaltkontakten und einem Magnetantrieb mit einem Anker, dessen Bewegung mittels eines Betätigungsmechanismus über einen schwenkbaren Hebel, wie einer Schaltwippe, die in dem Gehäuse mittels zweier Lager drehbar gelagert ist, zum Bewegen der Schaltkontakte zwischen einer Öffnungsstellung und einer Schließstellung übertragbar ist und wobei die das Wippenlager aufnehmenden Lagersitze geteilt sind, wobei ein Lagersitzteil mit einem U-förmigen Querschnitt von einem Halbkreis mit zwei ungleich langen Schenkeln gebildet ist und die Einführungsachse für das Wippenlager in den U-förmigen Lagersitzteil rechtwinklig zur Lastrichtung der beim Öffnen und Schließen der Schaltkontakte auftretenden auf das Wippenlager einwirkenden Lastkräfte ausgebildet ist.

Figure 00000001
The invention relates to an electromagnetic switching device with movable switching contacts arranged in a multi-part housing and a magnetic drive with an armature, the movement of which by means of an actuating mechanism via a pivotable lever, such as a rocker switch which is rotatably mounted in the housing by means of two bearings, for moving the switching contacts is transferable between an open position and a closed position and wherein the bearing seats receiving the rocker bearing are divided, a bearing seat part with a U-shaped cross section being formed by a semicircle with two legs of different lengths and the axis of insertion for the rocker bearing into the U-shaped bearing seat part at right angles is designed for the load direction of the load forces acting on the rocker bearing when the switching contacts open and close.
