Abstract

268,882. Reyrolle & Co., Ltd., A., and Anderson, W. Jan. 8, 1926. Oil-switches.-The arrangement of contacts is such that the arcing contacts E, E<1> carry the arc bodily downwards away from the gases evolved, as the contacts separate. For this purpose the contact carrying arms C, C<1>, which are horizontal or downwardly inclined, are rocked by means of springs F<4> which come into action on the breaking of a toggle, formed by links L, L', by a magnet N. The toggle is re-formed and the contacts re-set by a hand wheel K<2>. Fig. 8 illustrates a modified arrangement wherein the main contacts C<4> are bridged by a member C' which moves longitudinally downwards, the arcing contacts E<3>, E' acting as in the firstmentioned modification.
