Abstract
274,148. Nagy, O. Feb. 17, 1926. Addition to 247,961. Retractive switches; contacts. - In the compressible or extensible contact-making device of the parent Specification comprising a yielding tube containing contacts normally separate and brought together by compressing or extending the tube, wires 21, Figs. 1 and 2, are secured to a strip of fabric 22 which is wound helically to form a tube (so as to obtain relative, longitudinal displacement of the wires) and the fabric tube is covered by a rubber tube 23. Instead of using wires the inner tube may consist of a woven fabric made up of conducting and non-conducting threads in the form of a tape, Figs. 5 and 6 which is wound helically on a core, covered with a rubber tube, and the core then removed. The non-conducting threads may be dyed different colours so that the adjoining conducting threads may be identified at any part of the continuous tube. The conducting threads may be of tungsten, chromium or gold or may be coated with these metals. The inner tube may be filled with inert gas or with oil to prevent sparking. The outer tube may have longitudinal ribs adapted to hold the tube within a dovetailed groove of the support.
