Claims

[Scope of utility model registration request]

An input side optical receptacle disposed approximately at the center of the housing, a plane mirror disposed opposite to the input side optical receptacle and supported by a rotatable holder, and a plurality of output sides disposed on the circumferential surface of the housing. In an optical switch that includes an optical receptacle and a pulse motor that rotates the holder, the light from the input side optical receptacle is switched and reflected to one output side optical receptacle according to the rotational position of the plane mirror. A cylindrical shutter having a peripheral wall that blocks light and a transmission hole that is opened in a part of the circumference of the peripheral wall and that transmits the reflected light is arranged coaxially with the holder and configured to rotate together with the holder, An optical switch with a shutter is further provided with a mechanism for relatively rotating the shutter and the holder by a minute angle.
