ABSTRACT:
Electronic signals which are converted to light signals by means of a light emitting diode or laser diode are channeled through a fiber optic group and enter a rotary fiber optic switch. A rotatable drum channels and distributes the light signals to intended output locations by means of light conductive elements in the drum. Selecting the desired position of the drum by means of a detent switch or by mechanically rotating the drum by a light actuated mechanism determines the channel orientation of the device. The output signals emerge from the light conductive elements in the drum and are transmitted through output fiber optic groups to a photo diode or photo transistor where they are converted into electronic signals for normal electronic I/O processing.
