PROBLEM TO BE SOLVED: To provide a small sized optical switch with which a switching state of every individual transmission path is electrically monitored from the outside of the optical switch with high precision. SOLUTION: The optical switch is provided with a conductive member which is joined to an optical part and moves linked with the optical part and an electric circuit in which an electric connecting state is switched by the movement of the above conductive member. |
