PURPOSE: A noncontact mode optical switch is provided to connect low-loss optical signal and to facilitate array and attachment of a lens and to obtain convenient maintenance of the optical switch by connecting optical signal with certain bandwidth to a corresponding core mandrel as low-loss optical signal. CONSTITUTION: A noncontact mode optical switch includes a step motor(100), a carrier screw(110), a center port lens array(120), a center port fiber clamp(170), a coaxial supporter(150), and a lens array(130). The carrier screw is connected with an output axis of the step motor. The center port lens array, into which a micro lens is installed, axially and linearly moves via rotation direction of the carrier screw. Backward of the micro lens is installed the coaxial supporter. Forward of the lens array is installed another lens array in which a micro lens(134) inserted into a lens groove(132) and a lens cover(146) installed to a cover groove(144) are installed.
