Abstract

665,537. Electromagnetic switches. DONOVAN ELECTRICAL CO., Ltd., and FAIR, J. W. Oct. 23, 1950. [Oct. 22, 1949] No. 27183/49. Class 38 (v). To avoid vibration and to hold the operating coil d in position, coil springs e are arranged between the coil and the magnet core b which is mounted by means of rods b<SP>2</SP> on an insulating frame. The frame includes a backplate a, a top member a<SP>1</SP> and a bottom member a<SP>2</SP> against which the coil d is pressed by the springs.
