Claims

[Scope of utility model registration request]

A cylindrical yoke, consisting of an annular portion whose outer peripheral end surface is attached to the inner peripheral surface of the yoke, and a cylindrical portion provided within the yoke coaxially with the yoke! An iron core, a winding frame provided on the outer peripheral surface of the cylindrical part of the fixed iron core, a coil wound around the winding frame, and an annular magnetic pole made of a permanent magnet material attached to the end face of the cylindrical part of the fixed iron core. , a movable iron core installed so as to be in sliding contact with the inner circumferential surface of the winding frame and attracted to the magnetic pole when the coil is unidirectionally excited; and a movable contact that is pressed when the movable iron core is attracted and presses the movable contact against the fixed contact. An electromagnetic switch comprising a shaft, the front moving contact shaft being made of a non-magnetic material.
