Abstract

The invention relates to an electromechanical actuator for the gearbox of an automotive vehicle that comprises an actuation member (14) for controlling the movement of one or more internal members of the gearbox. It further includes a first cinematic chain and a second cinematic chain each adapted for implementing the actuation member and selection means (12) for selectively implementing said actuation member via one of said cinematic chains.
