  • Publication number: 20210217571
    Abstract: An electromagnet device moves two moving contacts from one of a closed position or an open position to the other position when an electric current flows through a coil. A regenerative current coming from the coil flows through a regeneration unit when the coil makes a transition from an energized state where the coil is supplied with an electric current from a power supply to a non-energized state where the coil is supplied with no electric current from the power supply. The control unit causes the regenerative current to flow through a load by controlling a switch when the coil makes the transition from the energized state to the non-energized state.

  • Publication number: 20210027964
    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.
