In some embodiments, a DC relay includes a pair of fixed contacts fixedly installed on one side of a frame, a movable contact movably installed below the pair of fixed contacts and brought into contact with the pair of fixed contacts or separated therefrom, an insulating plate installed below the movable contact, a contact spring provided between the movable contact and the insulating plate, a plate installed below the insulating plate and including a through hole formed in a central portion thereof, a fixed core inserted from above the plate through the through hole and including a shaft hole formed at the center thereof, an anti-noise pad provided between the fixed core and the insulating plate, a movable core installed to be linearly movable below the fixed core, and a shaft installed to penetrate through the through hole.

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.

A relay according to one embodiment of the present invention includes a housing, a cylinder, a fixed contactor coupled to the housing, a movable contactor contactable with or separated from the fixed contactor, a coil assembly disposed in the housing to generate a magnetic field, a movable shaft coupled with the movable contactor at an upper portion thereof, a fixed core inserted into the cylinder, a moving core fixed to the movable shaft to move the movable shaft in a pressing manner, a wipe spring to supply elastic force to the movable shaft, and a return spring located between the fixed core and the moving core. The moving core includes a cylindrical protrusion extending toward the fixed core and surrounding the movable shaft.

Disclosed embodiments relate to a direct current relay. In some embodiments, a direct current relay is capable of reducing noise by attenuating an impact generated between a fixed core and a moving core during an ON operation, and by attenuating an impact generated between a shaft and a middle plate during an OFF operation.
