Abstract
1,114,913. Electromagnetic contactors. WESTINGHOUSE ELECTRIC CORPORATION. 19 Sept., 1966 [15 Oct., 1965], No. 41634/66. Heading H1N. A polyphase electromagnetic contactor has an offset projection 40 on the contact surface 39 of each end of its resiliently mounted bridging contacts 37 so that after initial engagement of the projection with the fixed contact 35 the bridge tilts to the position shown in Fig. 5C. This is intended to cut through any undesirable film or surface material on the surface 46 of the fixed contact 35. The end of the projec
