Abstract

355,047. Switch bases. CRABTREE, J. A., Endwood, Little Aston, Sutton Coldfield. Sept. 4, 1930, No. 26377. [Class 38 (v).] A composite base for a switch comprises a body member made of moulded synthetic resin and a refractory member recessed and secured within the body member and adapted to house the fixed and moving current - carrying parts and isolate them from the body member. As applied to a tumbler switch, the central well on the moulded base is fitted with a porcelain lining b of the form shown in Fig. 5, which is secured by screws engaging slots b3 in the ends. The moving contact-arm swings in the recess b<1> and the working parts of the fixed contacts project through apertures b2 in the sides of the member b.
