Claims

[Claims for Utility Model Registration] (1) At least one pair of electrical contacts that are composed of a conductor and a contact fixed thereto and that open and close within a container, and an arc that occurs when the electrical contacts open and close. and a light absorber having opposing surfaces facing non-parallel to each other so as to sandwich the light absorber from both sides, and the light absorber is one of fibers, nets, and porous materials with an apparent porosity of 35% or more. Or a switch characterized by being composed of two or more types of composite materials. (2) The switch according to claim 1, wherein the opposing surfaces of the light absorber are non-parallel so that the distance between the opposing surfaces decreases in the direction in which the movable electric contact opens. (3) The switch according to claim 1, wherein the opposing surfaces of the light absorber are non-parallel so that the distance between the opposing surfaces increases in the direction in which the movable electric contact opens. (4) The opposing surfaces of the light absorber are non-parallel so that the distance between the opposing surfaces increases in the direction along the fixed electrical contact and away from the movable electrical contact. Switch mentioned in section. - (5) The opposing surfaces of the light absorber are made non-parallel so that the distance between the opposing surfaces decreases in the direction along the fixed side electrical contact and away from the movable side electrical contact. Switches listed in scope 1. (6) The switch according to claim 1, 2, 3, 4, or 5 of the utility model registration claim, wherein the surface of the light absorber is hardened by heat treatment. (7) Utility model registration claim 15, in which the light absorber is formed as a main component of magnesia or zirconia;
The switch according to item 2, 3, 4, 5 or 6.
