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.
