An apparatus and method for switching waveguides between a junction waveguide and a bypass waveguide among a plurality of housing ports. The apparatus comprises a housing having a first, second and third housing port and a waveguide rotor, having a first and second rotary position. The waveguide rotor includes a junction waveguide, having a first, second and third junction port, for combining the first, second and third housing ports in the first rotary position and a bypass waveguide, having a first and second bypass port, for connecting the first and second housing ports in the second rotary position. The junction and bypass waveguides are alternately selectable by rotating the waveguide rotor to the first and second rotary positions. The method comprises rotating a waveguide rotor including a junction waveguide having a first, second and third junction port and a bypass waveguide having a first and second bypass port, to a first rotary position in a housing including a first, second and third housing port, whereby the first, second and third junction ports connect the first, second and third housing ports and rotating the waveguide rotor to a second position a bypass waveguide, whereby the first and second bypass ports connect the first and second housing ports.
