An electromagnetic system includes a magnetic yoke, a coil mounted in the magnetic yoke, a lower iron core disposed in a lower portion of the coil, a top plate disposed above the coil, an upper iron core having a lower portion disposed in the coil and an upper portion extending through the top plate, an armature disposed above the top plate and fixedly connected to the upper iron core, a magnetic isolation ring disposed between the upper iron core and the top plate, and a plurality of balls each rolling in one of a plurality of first curved grooves of the armature and one of a plurality of second curved grooves of the top plate. The upper iron core moves in a vertical direction. A force applied on the armature by the ball is inclined to a central axis of the upper iron core to drive the armature to rotate.

An electromagnetic relay includes a relay including an electromagnet, a contact which opens and closes in accordance with operation of the electromagnet, and an inner housing in which the electromagnet and the contact are accommodated, a support member on which the relay is elastically supported, an outer housing in which the relay is accommodated, and a weight which is attached to the relay.

A power relay for a vehicle is disclosed. The power relay has a housing formed by a connector base and a housing can set thereon, two connection bolts being inserted into the connector base for contacting a load circuit. The power relay further has a coil subassembly arranged in the housing and containing a solenoid coil and an armature. The armature is coupled by a force-transmission member to a contact bridge and can shift in the housing, under the effect of a magnetic field generated by the solenoid coil, in such a way that the contact bridge can be reversibly moved between a closing position, in which the contact bridge bridges the connection bolts in an electro conducting manner, and an opening position, in which the contact bridge is not in contact with the connection bolts. The housing can is configured as an injection-molded component made of plastic.

An arrangement for an electric switching device is disclosed. The arrangement for an electric switching device comprises a switching unit having a first switching position and a second switching position, a restoring element exerting a restoring force on the switching unit in the second switching position, and a return spring fastened to the switching unit and exerting a counterforce on the switching unit. The restoring force is directed toward the first switching position, while the counterforce acts opposite to the restoring force.
