A contact module includes a pair of contact devices, each of which includes a fixed terminal and a moving contactor. The moving contactor moves from a closed position where the moving contact is in contact with the fixed contact to an open position where the moving contact is out of contact with the fixed contact, and vice versa. One moving contactor generates, when energized, a magnetic field that applies force to the other moving contactor in a direction from the open position of the other moving contactor toward the closed position of the other moving contactor. The other moving contactor generates, when energized, a magnetic field that applies force to the one moving contactor in a direction from the open position of the one moving contactor toward the closed position of the one moving contactor.

A magnetic system of an electromagnetic relay comprises a coil, an iron core, a yoke, and an armature. The iron core extends through the coil and has a first end and a second end opposite to the first end. A second part of the yoke is connected to the first end of the iron core and a first part of the yoke extends in a length direction of the iron core and is separated from the coil. The armature is disposed at the second end of the iron core and has a main body and a bending portion bent from the main body by a predetermined angle. The main body faces an end surface of the second end of the iron core. The bending portion is disposed at an inner side of an end portion of the first part of the yoke and faces the iron core.

A method for closing an actuator in a magnetically actuated switch assembly, where the actuator includes an armature and a winding, and the switch assembly includes a manual actuation device coupled to one end of the armature and a movable terminal in a vacuum interrupter coupled to an opposite end of the armature. The method includes commencing a closing operation of the actuator using the manual actuation device to move the armature towards a closed latch position, detecting that the actuator is being manually closed, and energizing the winding to assist moving the armature to the closed latch position when the armature gets to a predetermined distance from the closed latch position.

A yoke assembly for an electromagnetic switching device is disclosed. The yoke assembly comprises a yoke and an elastic deceleration element. The yoke has a support face supporting an abutment face of an actuating assembly in a position of the switching device. The elastic deceleration element is mounted on the yoke and has a deceleration face disposed at a distance from the support face.

An electromagnetic relay including: an electromagnet; a movable spring having a movable contact; a first terminal to which one end of the movable spring is connected; a second terminal having a fixed contact opposite to the movable contact; an actuator that rotates by excitation of the electromagnet, rotates the movable spring, and causes the movable contact to come in contact with the fixed contact or to separate from the fixed contact; a nonmagnetic card to be attached to the actuator; a plurality of magnetic members that sandwich the movable contact and the fixed contact, and apply a magnetic flux to the movable contact and the fixed contact to extend an arc; and a permanent magnet attached between the magnetic members.

At the time of contact between the contacts, the first movable contact comes into contact with the first fixed contact before contact between the second movable contact and the second fixed contact is made. The first movable contact is located on a leading end side of the contact piece with respect to the second movable contact. The first divided piece includes a body and a projection. The body extends in the lengthwise direction. The projection projects in the widthwise direction of the first divided piece from the body. The projection includes a contact portion pressed by the link member.
