A non-contact type coaxial switch that eliminates all contacts and inner conductors. The switch includes a stator/coax base assembly and a rotor. The stator/coax base assembly is fixed, while the rotor is rotatably mounted to the stator/coax base assembly and eliminates all contacts and inner conductors. The rotor is disposed between bearings, and consists of waveguide paths that couple between selected coax connectors. When the rotor is rotated, different selected coax connectors occur. For other arrangements selected, the rotor can switch between a condition of coax and waveguide outputs. The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs. The switch can assume many configurations. For example, a Double-Pole-Double-Throw (DPDT) configuration; a 3 and 4 Way R-Type configuration; a Single-Pole-Multiple-Throw (SPMT) configuration; a T-Switch configuration; and a Multiple-Pole-Multiple-Throw (MPMT) configuration.
