Abstract
449,797. Making switch contacts; welding. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Feb. 1, 1936, No. 3104. Convention date, Feb. 1, 1935. [Classes 83 (ii) and 83 (iv)] A switch contact member is formed of a silver facing member 13 united to a steel body member 14 by rolling &c. The member 14 is positioned on a carrier member 17 by tapered projections 15 engaging a groove 16 in the carrier and the members 14, 17 are then united by resistance welding.
