Abstract
A switch (11) for a square coaxial network includes a lower housing (13), a rotor assembly (21), alternative transmission lines (19), and an upper housing (15) with a main transmission line (17). The rotor assembly includes a rotor (23) for selectively coupling the main transmission line to a selected alternative transmission line. The rotor is coadapted with each transmission line for resonant coupling therewith. A conductive shield (29) rotates with the rotor and isolates it from the unselected alternative transmission lines. A low-friction dielectric guide (25) helps provide proper spacing and coupling of the rotor and the square center conductor (35) of the selected alternative transmission line. A low-friction dielectric bushing (27) serves a similar function for the rotor and the center conductor of the main transmission line.
