Claims

[Scope of utility model registration request]

(1) At least one pair of umbrella electrical contacts consisting of a conductor and contacts fixed to the conductor, which open and close within the container, and an arc generated between the contacts in a certain direction when the contacts open and close. a magnetic flux plate or a magnetic flux plate and a permanent magnet driven by the arc, and a light absorber arranged to sandwich the arc from both sides, and the light absorber is made of fibers, nets, and porous materials with an apparent porosity of 35% or more. A switch characterized in that it is constructed of a composite material of one or more of the above materials.

(2) The switch according to claim 1, wherein the surface of the light absorber is hardened by heat treatment.

(3) The switch according to claim 1 or 2, wherein the light absorber is composed mainly of magnesia or zirconia.

(4) Equipped with an arc extinguishing chamber that extinguishes the arc driven in a certain direction, and this arc extinguishing chamber is made of a de-ion arc extinguishing plate made of a plurality of magnetic materials and an insulating material supporting both sides of this arc extinguishing plate. A switch according to claim 1, 2, or 3 of the utility model registration claim, which comprises a side plate.
