A joy stick controller apparatus comprises a lever(12) mounted for pivotal motion in at least two directions, a guide(18) defining a preselected shift pattern(20) for the lever(12), and an indicating arrangement(30) for producing a digital logic representation of the position of the lever(12) relative to the shift pattern(20). The indicating arrangement(30) comprises energy actuated members(40) positioned at predetermined locations relative to the shift pattern(20), energy producing members(50) positioned in registry with the energy actuated members(40) for normally actuating the same and shield members(60,62) interposed between the energy producing members(50) and energy actuated members(40) and movable in response to movement of the lever(12) into positions for respectively permitting and preventing actuation of the energy actuated members(40) by the energy producing members(50) in a predetermined fashion such that said energy actuated members(40) collectively form a representation of the location of the lever(12) relative to the shift pattern(20). |
