An optical switch device for driving a movable member mounting a light reflection member thereon by a magnetic drive circuit, wherein, in an optical waveguide switching device ( 1 ) as an optical switch device, a movable member ( 2 ) mounting thereon an optical waveguide switching prism mirror ( 2 ) is driven in an X direction by a magnetic drive circuit while being floated from a fixing-side member ( 13 ) in order to improve stability of a light outputting position. When the movable member ( 2 ) is moved to a desired position in the X direction, power supply to solenoids ( 45, 46 ) is stopped in a clamp mechanism ( 40 ), and a clamp plate ( 41 ) presses the movable member ( 2 ) against the fixing-side member ( 13 ) to fix it. A V-groove ( 30 ) formed in the movable member ( 2 ) and a V-groove ( 31 ) formed in the fixing-side member ( 13 ) mesh each other to position the movable member ( 2 ) in the X direction.
