This paper describes new optical switch modules based on Risley optical beam deflectors. The Risley deflector consists of two wedge-shaped prisms and precisely controllable rotation mechanisms. An optical beam can be deflected to the direction of two axes by rotating each prism independently. The deflectors potentially have a self-latching function, which provides a reliable switching operation, and a large-deflection angle of 19.2°, which makes the switch compact. We experimentally confirmed that prototype switch modules, hardware volume: $15\times 15\times 31$ mm3, deflection angle: ${<}19.2$°, have a scalability of the switch up to 256 ports, low-loss characteristics of 1.0–1.5 dB, and switching time of within 6 s.
