Abstract

810,074. Keyboard switches; switchboards. STANDARD TELEPHONES & CABLES Ltd. March 22, 1957 [March 28, 1956], No. 9510/57. Class 38 (5). [Also in Group XXXIX] A jack, key or lamp strip is built up of individual units bolted and keyed together between end-pieces.. Each unit comprises a moulded frame carrying contacts and has flange-like projections and corresponding recesses at the corners of each end to key with adjacent units. End-pieces 41, 42 at each end of a strip mate with the projections and recesses of the end units and may carry strip mounting blocks 45, 46. A bolt passes through a bore in each unit and the bore may have a slot opening 64 so as to engage the flattened shank of the bolt by passing it edgewise through the slot into the bore (Fig. 9, not shown). More than one bolt may be used to secure the units. A metal key 51, Fig. 8, has a pin 63 guided in slots 61, 62 in the frame, and formations 55, 56 co-operating with contacts 4, 5. If the key is pulled out to separate 55 from 4, circuit is broken between 4, 5. If the key is pulled out further, 55 engages 5 and prevents loose movement.
