Abstract: A method is for controlling an electromagnetic relay comprising a fixed contact, a movable contact that comes in contact with and separated from the fixed contact, an electromagnet that includes a coil for generating magnetic field, and an actuator that moves the movable contact. The method includes: when separating the movable contact that is in contact with the fixed contact, supplying a first current to the coil to generate a first magnetomotive force that drives the actuator in a direction to move the movable contact toward the fixed contact, supplying a second current to the coil, while the first current is supplied to the coil, to generate a second magnetomotive force that drives the actuator in a direction to move the movable contact away from the fixed contact, and stop supplying the first current while the second current is supplied to the coil.

Abstract: An electromagnetic relay includes a fixed contact; a movable contact movable between a first position at which the movable contact contacts the fixed contact to form a closed state, and a second position at which the movable contact does not contact the fixed contact to form a opened state; an electromagnet that includes a coil, a magnetic core, and a yoke coupled to the magnetic core, and generates magnetic field; and an actuator that includes a pair of armatures, and a permanent magnet sandwiched by the pair of armatures, and moves the movable contact by the magnetic field generated by the electromagnet, wherein a magnetic circuit formed by the magnetic core, the yoke and the pair of armatures is closed at the opened state, and is opened at the closed state.
