Abstract

The present invention relates to a micro-optical switch and comprises an external frame having a plurality of holes inside; an internal frame positioned in the plurality of holes and having holes inside; light reflecting means positioned inside the holes of the internal frame; external magnetic substances positioned at both sides of the external frame; outside torsion hinge for connecting the external frame to the internal frame and having 45° to the magnetic field produced by the external magnetic substances; inside torsion hinge for connecting the internal frame to the light reflecting means and for being perpendicular to said outside torsion hinge; an outside coil wired in the internal frame; and an inside coil wired in the light reflecting means, and is characterized in that the light reflecting means and the internal frame are preferably rotated by the inside torsion hinge and the outside torsion hinge as an axis when a current is applied to the inside coil and the outside coil.
