PURPOSE: An optical switch is provided to prevent the leakage due to the overlapping of the optical path by changing the optical path with providing a plurality of rotation mirrors on each of the bobbins, respectively, thereby improving the reliability of switching. CONSTITUTION: An optical switch includes a body, a rotational axis, a plurality of bobbins, a first and a second driving members, a plurality of sub ports(120), a main port(110) and a plurality of rotational mirrors(400). A light beam inputs and outputs from/to the plurality of sub ports(120) is installed at one side wall of the body and is placed at a line. The light beam inputs and outputs from/to the main port(110) is installed on the other side wall of the body and is perpendicular to the line. And, the plurality of rotational mirrors(400) is installed on the outside of the bobbins.
