Abstract

568,750. Contacts. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., FRYDMAN, E., and SEIFLOW, G. H. F. Oct. 13, 1943, No. 16760. [Class 38 (v)] A contact spring set for a relay is made up of contact springs 6 separated by insulating spacers 7, each spacer being provided on each side with a layer 8 of thermoplastic material which, as the result of heat treatment after assembly, has fused and sealed the set against ingress of moisture. The set is clamped between plates 9, 10 by a screw 11 which is first preferably coated with insulating varnish. Later the set is fixed to a member 4 of the relay by screws 12, 13.
