A relay includes a movable contact piece having a first movable contact and a second movable contact, a first fixed terminal having a first fixed contact, a second fixed terminal having a second fixed contact, a drive device configured to move the movable contact piece, and the wall portion disposed inside the first fixed contact and the second fixed contact in a longitudinal direction. At least a part of the wall portion is disposed at a position beyond the first fixed contact and the second fixed contact toward the movable contact piece in a moving direction of the movable contact piece. The movable contact piece has a shape so as to avoid the wall portion in a contact state where the first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact.

Component assemblies and methods of manufacturing component assemblies that include a magnetic yoke assembly for electromechanical contactors and relays are disclosed. In a particular embodiment, a component assembly that includes a magnetic yoke assembly for electromechanical contactors and relays is described. In this embodiment, the magnetic yoke assembly includes a movable contact and a ferromagnetic upper yoke mounted in above the moveable contact and separate from the moveable contact. The magnetic yoke assembly also includes a ferromagnetic lower yoke mounted under the moveable contact.

An electromagnetic relay includes a fixed contact, a moving contact, an electromagnet device, and a second coil. The moving contact 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. The electromagnet device includes a first coil and a mover. The mover is actuated on receiving a magnetic flux generated when a current flows through the first coil to move the moving contact from one of the closed position or the open position to the other position. The second coil gives, when a current flows through the second coil, at least a magnetic flux, of which a direction is opposite from a direction of the magnetic flux generated by the first coil, to the mover.
