ABSTRACT:
An optical switch (10) comprises a body of resilient material (12) including resilient opaque material (16) and resilient light conducting material (14). The light conducting material (14) is arranged in rows (20) and columns (22) which intersect at junctures (30). At least one light transmitter (50) directs light into one end of the rows (20) and columns (22) and through the junctures (30). Each juncture (30) is deformable to modify the intensity of light transmitted through the juncture (30). At least one light receiver (52) receives the light transmitted through the juncture (30) and provides an output signal in response to the modified light intensity.
