1. A micromechanical optical switch, comprising:

  • a reflective surface having two angled reflective surfaces;

    a micromechanical device, comprising;

    a reflective member, supported by at least one hinge;

    at least one electrode underneath said member, such that when said electrode is activated, said member deflects towards said electrode, but does not contact any surface; and

    said micromechanical device positioned opposite said reflective surface such that light impinging upon a first of said angled reflective surfaces directs light to said reflective member of said micromechanical device and a second of said angled reflective surfaces receives light from said micromechanical device, wherein said second angled reflective surface receives light at a position dependent upon the deflection of said reflective member.
