Claims

[Scope of utility model registration request]

(1) A self-returning electromagnetic device, an idler that interlocks with the movable core of this self-returning electromagnetic device, a rotor that rotates clockwise and counterclockwise due to the engagement of this idler, and A toggle spring with one end stretched, and a movable contact rotatably supported by the rotor and moving toward and away from the fixed contact, the rotor rotating when the self-resetting electromagnetic device is driven. In an electric switchgear in which the movable contact is brought into contact with and separated from the fixed contact by the toggle action of the mover and the toggle spring, a permanent arc-extinguishing member is provided on the opposite side of the fixed contact to the contact facing part with respect to the movable contact. An electric switchgear characterized by being equipped with a magnet.

(2) The electric switchgear according to claim 1, wherein a U-shaped arc-extinguishing plate is provided in the base, in which the opposing contact portions of the fixed contact and the movable contact are disposed.
