Abstract

Autonomous control mechanism (100) for a movement, comprising a control stem (10) moveable relative to a bar (80) between stable stem positions, for controlling the pivoting, in each of said positions, of a single control train of the control trains of said mechanism (100).It includes, on a first side (81) of said bar (80), a first control train (810), and on a second side (82) opposite said bar (80), a second control train (820). Every stable position of the control stem (10) drives a stable position of a pull-out piece (20) fitted to one of said sides and moveable relative to a boss (210) of said bar (80). In said stable pull-out piece position, any movement applied to the control stem (10) causes the pivoting movement, of either a single first control train (810), or a single second control train (820).
