Claims

[Scope of utility model registration request]

The proximal end of the iron core around which the electromagnetic coil is wound is fixed to the yoke, and protrusions are provided on the yoke to protrude from the magnetic pole faces formed on both sides of the tip of the iron core, facing each other at a predetermined distance. a movable block having a pair of iron pieces arranged at both ends of a permanent magnet and fixed to a movable insulating table, and each iron piece arranged between the protrusion piece and the magnetic pole face; It is equipped with a contact mechanism that is opened and closed in conjunction with the movement of the movable block, and when the electromagnetic coil is energized, one of the pair of iron pieces is attracted to the magnetic pole surface of the iron core, and the other is attracted to the protruding piece of the yoke. In a polarized electrode relay configured to move a movable block in a direction perpendicular to the longitudinal direction of the iron core, a notch recess is formed in one of both magnetic pole surfaces of the iron core, and the above-mentioned A polarized electromagnetic relay characterized in that it is configured so that the attracting surfaces of iron pieces are in contact with each other.
