Abstract

240,312. English Electric Co., Ltd., and Morris, F. Oct. 30, 1924. Drawings to Specification. Master control systems. - In the control of electric traction motors a reversing switch actuated by solenoids or other means under the control of a master switch is biassed to return to an intermediate " off " position and is provided with separate sets of auxiliary contacts in order to complete separate actuating and maintaining circuits. When the reversing switch is required to return to the intermediate position the maintaining circuit is broken by a return movement of the master switch, or as a consequence of the opening of a line circuit-breaker.
