Claims

[Scope of utility model registration request]

At least one pair of electrical contacts consisting of a conductor and a contact fixed thereto, which open and close within the container, and a magnetic material, arranged at a predetermined distance, and generated when the contacts open or close. A plurality of de-ion arc-extinguishing plates extinguishing arcs, and a magnetic material, supporting both sides of the de-ion arc-extinguishing plates, and forming a magnetic circuit for arc attraction with the de-ion arc-extinguishing plates. A switch comprising a side plate, the side plate being made of a composite material of one or more of fibers, nets, and porous materials with an apparent porosity of 35% or more.
