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.

A sequential actuator for a radio frequency switch includes a rotor designed to be rotated in a designated rotational direction of the actuator and a stator defining with the rotor when the stator is energized an active torque curve of the rotor having asymmetric positive and negative torque curve portions. Magnetic elements are distributed between the rotor and the stator and define a detent torque curve of the rotor. In some examples, when the stator is energized, the rotor undergoes a first rotation from a position of partial angular overlap of a first rotor magnetic element with a first stator electromagnet to a position of angular alignment of the first rotor magnetic element with the first stator electromagnet. Upon reaching this angular position, a second rotor magnetic element has a partial angular overlap with a second stator electromagnet and the rotor further undergoes a second rotation to another position of angular alignment of the second rotor magnetic element with the second stator electromagnet.

Waveguide hinges are provided that allow for a substantially continuous RF waveguide to be formed through the hinge when the hinge elements are in a particular relative rotational configuration with respect to one another; the substantially continuous RF waveguide is not formed when the hinge elements are in various other relative rotational configurations. Such waveguide hinges allow for waveguide elements to be repositioned during periods when RF energy is not being transmitted.
