Abstract: 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.

Abstract: Disclosed is a relay. The relay includes a first fixed contact, a second fixed, a movable contact, and a first magnet and a second magnet. The first contact part is disposed at a position which is closer to a distance to the second magnet than a distance to the first magnet, and the second contact part is disposed at a position which is closer to the distance to the first magnet than the distance to the second magnet. Accordingly, arcs are prevented from gathering at one position, and a contacting force between the movable contact and the fixed contacts is prevented from being reduced.
