A fiber optic control device having a joy stick lever (10), a housing (14, 16) which mounts the joy stick lever (10) for universal pivotal movement on the housing (14, 16) from an upright axis thereof, a pair of mirrors (42, 72) which are movably mounted on the housing, driving connections between the joy stick lever (10) and the mirrors (42, 72), for actuating the latter in response to movement of the joy stick (10) a cooperable movement limiting device on said joy stick (10) and housing (14, 16) enabling said universal pivotal movement of the joy stick lever (10) to be had while preventing its rotative movement about the longitudinal axis thereof, and fiber optic light transmission devices (24, 26, 54) that are cooperable with the mirror and that can include source of light which are adapted to direct light beams against portions of the mirrors (42, 72), for providing output light signals in optical cables, which are a function of the virtual position of the joy stick lever (10).
