<P>PROBLEM TO BE SOLVED: To provide a switch (20) for selectively providing an input signal to an output terminal. Ž<P>SOLUTION: The switch 20 includes a first waveguide terminal 40, a second waveguide terminal 42, a reduced-width waveguide 26 connecting the first waveguide terminal 40 to the second waveguide terminal 42, and at least one switching element 34 spanning the reduced-width waveguide 26 between the first and second waveguide terminals 40, 42. The reduced-width waveguide 26 is configured to pass a signal from the first waveguide terminal 40 to the second waveguide terminal 42 when the at least one switching element 34 is in a first state and block a signal when the at least one switching element 34 is in a second state. In some embodiments, the switch also includes at least one additional waveguide terminal 59 and the reduced-width waveguide also connects the first waveguide terminal to the at least one additional waveguide terminal.
