Abstract
Abstract An optical rotary control device (10) is provided comprising a light source (12) and at least one light receptor (14) linearly spaced, creating a planar axis with the light source (12). A rotatable light director (16) is provided which includes means for directing light from the light source (12) to at least one optical aperture (22) in the light director (16). The optical aperture (22) refracts the directed light from the light director (16) to the light receptor (14). The optical rotary control (10) device further comprises an isolator portion (20) having recesses (24) for receiving and separating the light source (12) and light receptor (14). The means for directing light may include a cut out section (18) in one end of the light director (16 ).
