TRIES Inc 7 May 1971 [21 Aug 1970] 13793/71 Heading H2E A switched lamp socket comprises an insulating casing 10 of two separable halves 11, 12 formed with transverse walls 36, 37, 42, 43 forming end compartments housing socket contacts 13, 14 suitable for lamp bulbs interconnected by strips 15, 16 and an intermediate switch housing compartment 32. Electric supply conductors 27, 28 are connected respectively to a U-shaped member 20 riveted to the strips 15, 16 and to a base contact member 25, which members are held, when the socket is assembled, in engagement with the casing halves 11, 12 by the ends 64, 66 of holding posts 63, 65 integral with the halves 12, 11. Two resilient contact elements 53, 54 are clamped between notches 49, 50 in the walls 42, 43 and the walls 36, 37 such that prongs 67, 69 extend into the socket-housing compartments and prongs 68, 70 into the switch-housing compartments where they are contactable with fingers 60, 61 of the base contact 25. A switch 81 comprises a shank 80 rotatably mounted in grooves 79a, 79b in the casing halves with an actuating head 83, rotation causing the head to engage the prongs 68, 70 and move them into contact with the fingers 60, 61.
