摘要： A switch comprising a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc. The switch according to the present invention is applicable to a switch expected to generate an arc upon interruption of electric current flowing therethrough such as a circuit breaker, current-limiting device or electromagnetic contactor and is capable of immediately extinguishing the arc and inhibiting the decrease in insulation resistance within and around the arc extinguishing chamber and at inner wall surfaces of the switch case.

摘要： A polyester resin composition comprising 21-29% by weight of a resin component consisting of fumaric acid neopentyl glycol propylene glycol type polyester and cumene hydroperoxide as a hardening agent; 52-60% by weight of one or more kinds of inorganic compounds which undergo dehydration reaction at a temperature not later than 150.degree. C. as an inorganic filler; and 15-23% by weight of a reinforcing material. The composition of the present invention when used for an insulation component member of a switch, improves the insulation property after the cut-off of a large electric current. More specifically, the composition of the present invention can prevent the formation of the resin skin layer on the surface of the molded product, so that the inorganic compound which can be decomposed by the heat from the electric arc to produce a gas which changes the free carbon and metal vapor to nonconductive oxides can be present in the surface layer of the molded product and the insulation property can be secured even after the cut-off of the electric current.

摘要： An organic and inorganic complex composition wherein the resin is at 15-70 wt % and the content of one or more inorganic compounds capable of dehydration at 150° C. or more is at 80-30 wt %. When the composition is exposed to combustion, inorganic compounds being capable of dehydration at 150° C. or more and being contained in the organic and inorganic complex composition generate steam which then suppresses combustion. Simultaneously, endothermic reaction during steam generation deprives combustion heat. A switch having a molded article of which the entirety or a part is composed of an organic and inorganic complex composition is provided, wherein the base inside of the base of a box is composed of for example an organic and inorganic complex composition with the resin content at 15-70 wt % and the content of one or more inorganic compounds capable of dehydration at 150° C. or more at 80-30 wt %.
