Abstract

787,996. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd. Oct. 31, 1955 [Nov. 2, 1954], No. 31655/54. Class 38 (5). In a relay in which the contact springs 11, 12 are mounted in a support 10 as disclosed in Specification 728,891, each moving spring 12 (only one shown) engages a slot in an operating bar 13 by means of a cylindrically-shaped end and co-operates on either side of the bar 13 with the twin contacts of fixed springs 11. The cylindrically-shaped end resiliently engages the opposed sides of the slot and manufacture of the bar 13 is facilitated owing to the greater width of the slot required to accommodate the enlarged spring end. The fixed contacts 11 may have cylindrically-shaped free ends, or they may be formed of rod or wire.
