摘要： An electromagnetic relay includes an electromagnet unit, an armature supported so as to be pivotable relative to a yoke by a hinge spring, a contact including a first contact and a second contact, which can switch, in accordance with pivoting of the armature, between a closed contact state and an open contact state, an elastic member which elastically deforms in accordance with pivoting of the armature, and applies a contact force between the first contact and the second contact in the closed contact state, and a magnet which generates an attractive force for retaining the armature in an open contact position corresponding to the open contact state, wherein the armature is retained in the open contact position by a resultant force of a restoring force applied to the armature by the hinge springe, and the attractive force of the magnet.

摘要： An electromagnetic relay includes a mobile component movable at time of energization and de-energization of a coil, and a fixed component immovable at the time of energization and de-energization of the coil. A damping space is provided between the mobile component and the fixed component and changes in volume with the movement of the mobile component. A gap provided between the mobile component and the fixed component serves as a passage that allows gas to flow into or out of the damping space when the damping space changes in volume. A size of the gap is set such that a pressure is generated in the damping space to cause a damping force acting on the mobile component when the damping space changes in volume.

摘要： An alternating current contactor comprises a base and a magnetic yoke. The magnetic yoke is mounted on a bottom plate of the base. A magnetic yoke support for supporting and buffering the magnetic yoke is respectively provided at two sides of the magnetic yoke, wherein sidewalls at two sides of each magnetic yoke support, which are connected with the magnetic yoke are different in thickness. The magnetic yoke support of the alternating current contactor of the utility model has a simple structure due to the arrangement of an asymmetric eccentric structure. The up-down position of the magnetic yoke relative to the bottom plate of the base can be adjusted by changing an assembly direction of the magnetic yoke supports, thereby achieving the purpose of adjusting the total stroke of the product with high flexibility. When a dimension of a housing of a plastic part is abnormal, the magnetic yoke has a certain adjustment amount to ensure that the integral assembly of the product can be completed and the efficiency and reliability can be improved.

摘要： 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.

摘要： 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.
