    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 %.

    摘要: A current limiting device includes first and second contact members, each contact member having, at a first end, contacts defining a contact pair; a contacting pressure is applied to said contact pair; and a cylindrical insulator cylindrically surrounding the contacts when the contacts are closed. The device is arranged such that at least one of the first and second contact members is rotatably supported at a second end. Also, an electrical path is defined through which currents flow in substantial opposition to the first and second contact members and in opposite directions to each other. The first ends of the first and second contact members are positioned within the space defined by the cylindrical insulator in the closed contact state. The contact of at least one of the rotatably supported contact members is positioned outside of the space defined by the cylindrical insulator when the contacts are open.

    摘要: A switch includes a fixed contact having a first conductor portion connected to a terminal, a second conductor portion having a stationary contact, and a third conductor portion. The third conductor portion is disposed on the side of the other end of a moving contact to which a traveling contact is not mounted with respect to a position of the stationary contact, and on the side opposed to the terminal. The first conductor portion is disposed above a contact surface of contacts at a contact closing time, and is disposed below a contact surface of the traveling contact at a contact opening time. A position of the first conductor portion which can be surveyed from a surface of the traveling contact at an opening time of the contacts is coated with an insulator. Thereby, it is possible to provide an excellent current-limiting performance since an entire current path of the fixed contact generates electromagnetic force to stretch an arc on the side of the terminal, and since the arc is cooled by vapor generated from the insulator.
