ABSTRACT:
A dual switch for coupling a waveguide microwave switch to a coaxial microwave switch. The waveguide microwave switch has a waveguide hollow member and a waveguide rotating section rotatably mounted about a rotational axis within the waveguide hollow member at one end. The coaxial microwave switch has a coaxial hollow member adjacent to the one end of the waveguide hollow member and a coaxial rotating section rotatably mounted within the coaxial hollow member about an axis coaxial with the rotational axis. The waveguide microwave switch is coupled to the coaxial microwave switch by at least one set of cooperating magnets fastened at a given radial distance from the rotational axis to the waveguide rotating section and the coaxial rotating section respectively, such that any rotation of the waveguide rotating section about the rotational axis will be followed by a corresponding rotation about the rotational axis of the coaxial rotating section. The set of magnets includes two magnets located radially opposite each other on the waveguide rotating section near its end and two pairs of magnets located radially opposite each other on the coaxial rotating section so that the magnets are centered between the pairs of magnets and repulse each other. This eliminates any openings between the waveguide microwave switch and the coaxial microwave switch and thus any radio-frequency leakage between the two switches.
