Abstract
An optical switch is disclosed. A lock magnetic field is provided on the sides of a rotator with a magnetic surface. The magnetic field has a potential with two minima as reflective and non-reflective positions. At the reflective position, the reflective mirror on the rotator reflects light beams. The beam goes through when the rotator is at the non-reflective position. At the same time, the magnetic field firmly locks the rotator at its position. When a driving force is imposed on the rotator; it rotates from its current position to the other position and gets locked at the new position.
