A small size waveguide switch having a stationary body with four mutually perpendicular sides and a port on each side. A rotor is mounted on the body and has two coupling arc-shaped symmetrical channels, along with a mechanism for alternately bringing the rotor to two switching positions where the channels of the rotor differently connect in pairs the ports. The driving mechanism is a d.c. motor consisting of a permanent magnet coupled to one end of the rotor, and a toroidal stator associated with the stationary body and having polar shoes and energizing coils supplied with a direct current with the direction being set by the status of optoelectronic devices.
