Abstract

782,118. Unlatching switches. GENERAL ELECTRIC CO., Ltd., and JENKINS, G. H. July 22, 1955 [July 22, 1954], No. 21432/54. Class 38 (5). The initial opening movement of the operating handle of an isolator switch serves to trip a latch-type contactor in series with it. The isolator switch, not shown, is operated by rotation of a shaft 1 carrying a cam 2, initial movement of which lifts arms 4 pivoted at 5 and thereby operates two Bowden wire controls 8, one of which trips the latch of the contactor and the other unlocks the cubicle door.
