Abstract

1,131,851. Two-part couplings. ENGLISH ELECTRIC CO. Ltd. 8 Feb., 1966 [10 Feb., 1965], No.5788/65. Heading H2E. [Also in Division H1] A casing 11 houses a withdrawable cradle 12 carrying a relay, and the cradle has a support member 59 carrying contact members 63, 64, spring-urged towards contact members 42 mounted on the support member 20 carried by the casing. Unlocking of a latch 93 from a catch 32 to allow the withdrawal simultaneously opens an isolating switch 82 via an L-shaped member 98 to break all the connections between the contact members (see Division H1). The contact members 42 provide terminal connections 47 for leads to apparatus external of the relay.
