Abstract

584,050. Electromagnetic switches. WEST & CO., Ltd., A., and PAVITT, F. J. Nov. 20, 1944, No. 23028. [Class 38 (v)] In an electromagnetic switch, the magnetic frame 31, which attracts the armature 32, is resiliently supported by leaf springs 47 so that engagement is made with the minimum of shock. The invention is applicable to a switch as described in Specification 549,421. Shading coils 50 may be provided.
