Claims

[Scope of utility model registration request]

At least one pair of electrical contacts consisting of a conductor and a contact fixed thereto and operating to open and close within the container; a plurality of arc-extinguishing plates disposed in a substantially U-shape with the tip side of the conductor of one of the pair of electric contacts opening toward the main surface side of the conductor; At the same time, the tip of the vertical piece on the load side of the substantially U-shaped tip extends toward the power supply side as a contact fixing piece, and the arc runner is exposed toward the tip side facing the contact side of the contact fixing piece. is fixed to the conductor of one of the electric contacts, and a substantially V-shaped notch facing toward the contact is formed at the tip of the arc runner.
