Abstract: A device comprising means capable of emitting an electrical signal and means responsive to said signal and adapted to command a change of gear. The means capable of emitting the signal include a light source which can be caused to communicate with a receiver element capable of triggering the electrical signal, and two rotatable shafts, the angular amplitudes of whose rotations depend respectively on engine operating parameters. The two shafts cooperate with means for causing the light emitter and receiver to communicate. Application to the control of an automobile gearbox.
