  • High switching speed, coaxial switch for R.F. signals
    Patent number: 4870385
    Abstract: A coaxial switch assembly includes a conventional reed switch (10) having a somewhat irregular enclosure (11) and protruding leads (20, 21). R.F. connectors (24, 25) are mounted at the ends of the leads, which are surrounded by predetermined lengths of dielectric tubular material (23). Electrically conductive flowable material (39) is injected within a surrounded shell (36) to fill the space remaining in a shell aperture (37) to rigidify the assembly and provide a continuous coaxial electrical conductor joining the outer body (27, 31) of the R.F. connectors to one another.
