Abstract

172,998. Creed & Co., Ltd., and Lenaghan, T. June 26, 1920. Relays with multiple contact-springs. A relay, particularly suitable for telephone switchboards of small capacity, is constructed so as to be readily fitted into position, or disconnected, bodily without interfering with the wiring of the exchange system. Fig. 1 illustrates the invention as applied to a relay of the type described in Specification 172,041. A mounting-plate b carries on an extension d a number of insulated strip-members e to which the leads are permanently soldered. The relay member is formed with a backplate a the upper portion of which carries the connecting tap and contact springs f of the relay. These project outwards and automatically make contact with the strips e as the relay is brought into position against the mounting-plate b. The relay is secured by means of screws C passing through the plates a, b. The ends g of the strips e may be curved, tapered, and staggered as shown in plan, Fig. 2, to facilitate contact with the members f.
