Miniature non-shorting telephone plugs designed for use with TT-Jax, Unijax, and other phone jacks with a .176" inside diameter bushing. Approximately 1/2 the size of standard phone plugs, yet retains the uniformity, dependability and quality of MIL-type phone plugs. TT-Plug Miniature Telephone Plugs are the first to offer 2- and 3-conductors in an attachable type with twist handles for quick assembly. Other color handles available on special order. Plugs feature a one-piece tip rod, ring and a one-piece sleeve with integral plug body, assembled together into a mold as inserts. Providing complete continuity of thermoplastic insulation between tip rod, ring and sleeve. Internal interlock of all parts prevents shifting and shorting under extreme rugged usage. Internal 12-24 threads in end of plug body are intended for threading over outer jacket of a patch cord to provide a superior cable anchor. Patch cords such as Switchcraft Series TT700 (or other .216" diameter cable) are easily attached to Series TT250 by screw terminals.
