    摘要： An electromagnetic contactor has a contact device having a pair of fixed contacts and a movable contact; and an electromagnet unit including an exciting coil driving a movable plunger connected through a connecting shaft. The contact device is configured such that L-shaped portions have a contact portion formed in the pair of fixed contacts fixed maintaining a predetermined interval, and two ends of the movable contact are disposed to be capable of contacting to and separating from the contact portions of the L-shaped portion on a side opposite to that of the electromagnet unit. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger having a leading end protruding through an aperture formed in the magnetic yoke and urged by a return spring, and a ring-form permanent magnet magnetized in a movable direction of the movable plunger and fixed to enclose a peripheral flange portion.

    摘要： An electromagnetic switch has a contact device having a pair of fixed contacts fixed inside an arc extinguishing chamber housing and a movable contact disposed to contact with and separate from the fixed contacts; and an electromagnetic device having a movable plunger moving between an opened position wherein the movable contact separates from the fixed contacts and a closed position wherein the movable contact contacts with the fixed contacts and pressed down. The arc extinguishing chamber housing is provided with permanent magnets to extinguish an arc generated at an opening time when the movable contact separates from the fixed contacts from a state in the closed position wherein the movable contact is contacting with the fixed contacts. In a state wherein the movable plunger is in the opened position, a magnetic circuit is formed starting from the permanent magnets and returning to the permanent magnets through the movable plunger.
