Abstract:
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.
