A 3D microwave switch having a plurality of waveguide transmission lines configured in a polyhedron and with I/O microwave ports at the corners. An actuator selectively moves respective reeds in the waveguide transmission lines between a signal-attenuating position abutting the interior surface of the waveguide transmission line and a signal-conducting position substantially coaxial with the waveguide transmission line and abutting the signal lines of the I/O microwave ports coupled to opposite ends of the waveguide transmission line. Preferably, the transmission lines and ports are formed in a tetrahedral-shaped conductive cavity with a single 4- pole magnet at its center for actuating the reeds or in an octahedral-shape with different actuators for each reed.
