Claims

[Scope of utility model registration request]

A magnetic circuit is constructed so that the iron core, auxiliary iron plate, permanent magnet, and iron core frame are arranged in series in this order. In an electromagnetic relay in which a substantially dogleg-shaped movable iron piece is extended to the vicinity of the plane, the tip thereof is used as a hinge point, a substantially dogleg-shaped movable iron piece is swingably supported, and a coil is wound around the iron core.
One of the auxiliary iron plates protrudes from the center of the iron core frame by a magnetic insulation distance, and the arm part of the movable iron piece comes into contact with the protrusion when returning, and the arm part of the movable iron piece and the iron core frame come into contact with the protrusion. An electromagnetic relay characterized in that a permanent magnet and an auxiliary iron plate form a magnetic closed loop.
