摘要： An electromagnetic switch includes a pair of fixed contacts disposed and fixed in a contact housing case with a predetermined distance therebetween; a movable contact disposed in the contact housing case so as to contact and separate from the pair of fixed contacts; and an electromagnet unit which brings the movable contact into and out of contact with the pair of fixed contacts. The electromagnet unit has a magnetic yoke enclosing an exciting coil, a movable plunger having a contact pole surface facing the contact pole surface of the magnetic yoke, and a linking shaft which links the movable plunger and the movable contact, and magnetic paths through which a holding force is generated by external magnetic fluxes generated by a flowing current when the movable contact contacts the pair of fixed contacts, are formed on the contact pole surface of the magnetic yoke.

摘要： The electromagnetic contactor includes a contact mechanism including a pair of fixed contacts disposed to maintain a predetermined interval and a movable contact disposed so as to connect to and separate from the pair of fixed contacts, and an electromagnet unit that drives the movable contact. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger, a leading end thereof protruding through an aperture formed in the magnetic yoke and a peripheral flange portion being formed on a protruding end side, movement regulating portions that regulate movement of the peripheral flange portion of the movable plunger in an engaged position and released position of the contact mechanism, and a contact noise suppression member that suppresses contact noise when the peripheral flange portion of the movable plunger contacts the movement regulating portions.
