Abstract
272,893. Nagy, O., (Assignee of Deutsche Telephonwerke und Kabelindustrie Akt.-Ges.). June 15, 1926, [Convention date]. Addition to 247,961. Refractive switches; contacts. -In the construction described in the parent case in which the conductors are spaced by elastic insulating intermediate members, these members are made with gaps, notches, &c., so that when they flatten under pressure contact can be made in those gaps &c. As shown an outer conductor e having a paper wrapping f round it is normally separated from the central conductor a by a helicallywound rubber strip which has a conducting strip b within the helices and laid on the conductor a, thus forming enlargements on this conductor with which the outer conductor contacts on sumcient pressure being applied to flatten the elastic ring. The enlargements on the central conductor can take other shapes, and, if the central core is non-conducting, may themselves form the conductor.
