Control mechanism for a timepiece movement, including, in a housing in a main plate, a control stem that is movable in a longitudinal direction and including a groove cooperating with a stud comprised in a pull-out piece for actuating the pivoting of the pull-out piece on the main plate, this pull-out piece is held in position by a jumper spring, and the mechanism including a bridge cooperating with the main plate to confine the stem, and this bridge includes a housing in which there is a movable limiter piston, arranged to abut on one end of a trunnion comprised in the pull-out piece under the application of a force in a transverse direction substantially orthogonal to the longitudinal direction, to allow the release of the stem after a given travel of the limiter piston. |
