Abstract: The invention relates to a device and to a method for switching electrical load circuits (2), comprising an electromagnetic contactor (1) having a magnetic drive that is formed from a magnet yoke (1.1) by a magnet coil (1.2) and a magnet armature (1.3) to which a contact bridge (1.4) is coupled by means of a contact retainer (1.5) as a movable contactor contact, wherein in the switched-on state the contactor (1) generates a magnetic retaining force (F
H ) for contacting the contact bridge (1.4) having fixed contacts (A, B), wherein the retaining force (F
H ) results from a magnetic field generated by the magnet coil (1.2) and the retaining force (F
H ) is greater than an armature opening force (F
R ). According to the invention, an overload contact (M) is integrated in an exciter current circuit (5) of the magnet coil (1.2) in such a way that, if the exciter current circuit (5) closed and a movement of the contact bridge (1.4) against the magnetic retaining force (F
H ) occurs, the magnet coil (1.2) can be short-circuited by closing the overload contact (M).

Abstract: In an initial state where a push rod is pressed down, a base of a movable contact point board supporting a movable contact point makes contact with inclined protruding portions of a moving block by a second spring to be inclined. When the movable contact point makes contact with a fixed contact point following the projecting of the push rod, the base makes contact with stoppers. Thereafter, since the moving block alone rises, the movable contact point board rotates following the end edges of the stoppers according to release of the pressing by the protruding portion. Thereby the movable contact point largely slides and is displaced to the fixed contact point. Since a leg of a movable contact point plate that extends from the base and is provided with the movable contact point is in advance deflected by an arm portion of a pressing member, a contact pressure between the movable contact point and the fixed contact point is high from a moment of the contacting. An excellent wiping operation can be obtained by the large sliding displacement and the high contact pressure.
