Abstract
An electromagnetic switch with a housing provided with at least one magnet system, comprising a stator body of magnetic material having an oblong chamber accomodating a movable armature of magnetic material, with an exciter winding for the excitation of a magnetic field in the at least one magnet system. A swingably supported first arm which can be brought into motion under the influence of the excited magnetic field. To actuate a pair of contacts a swingably supported second arm is provided and on each of the first and second arms one end of at least one leaf spring acts. The first and second arms extend on either side of the chamber at right angles to the lengthwise direction thereof in such a way that each of them can swing about their support point in the direction of the armature which is movable in the chamber between the arms. The free end of the first arm is coupled to the armature, which has an operating element which acts on the second arm.
