Abstract

546,404. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd. Feb. 19, 1942, No. 2228. Convention date, Feb. 27, 1941. [Class 38 (v)] An elongated contact-carrying member 1 is moved longitudinally into one or other of its positions by alternate energization of electromagnets 5, 6, a spring 13, which moves over dead-centres, providing a snap-action. The spring 13 is mounted between two bell-crank levers 7 which are pivoted at 9 to the frame and at 11 to the ends of the bar 1 and arc-respectively engaged by plungers 26 on the electromagnets 5, 6, when these are energized. The bar 1 carries two pairs of bridging contacts, 28, 29 and 30, 31 each pair passing through a hole in the bar and being pressed apart by a spring 32 or 33.
