Abstract

877,036. Switching systems. CRABTREE & CO. Ltd., J. A., and MILLICAN, R. M. Oct. 6, 1959 [Oct. 16, 1958], No. 32990/58. Drawings to Specification. Class 38 (4). [Also in Group XXXVII] An electromagnetic contactor energized by rectified A.C. has an auxiliary switch which connects a capacitor in series with the A.C. side of the bridge-connected rectifier when the contactor closes.
