Abstract

618,333. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 18, 1946, No. 31064. Convention date, Oct. 22, 1945. [Class 38 (v)] In a shock-proof contactor, the verticallymoving core 10 carries a rack 11 engaging a pinion 13, a crank on which operates the contact member 5 through a link 21 and a second rack 23, having a weight counterbalancing the weight of the rack 11 and the core 10, engages the other side of the pinion. A spring 27 fixed to the rack 23 biasses the contactor tc the open position. The contact member 5 is pivoted at 6 and the contact 4 may be adjusted by a screw 35: The crank moves through approximately 180 degrees in operation.
