Abstract:
1. A control mechanism for a timepiece movement, including, in a housing of a main plate comprised in said mechanism, a control stem which is movable in a longitudinal direction, said stem including a groove cooperating with a stud comprised in a pull-out piece for actuating the pivoting of said pull-out piece on said main plate, said pull-out piece being held in position by a jumper spring, and said mechanism including a bridge cooperating with said main plate to confine said stem, wherein said control mechanism includes a means of limiting the travel of said stud of said pull-out piece, via a travel limiter including a limiter piston, said bridge includes a housing in which said limiter piston has limited mobility, said limiter piston is arranged to abut on one end of a trunnion comprised in said pull-out piece under the application of a force in a transverse direction substantially orthogonal to said longitudinal direction, to permit the release of said stem after a given travel of said limiter piston, and wherein the mechanism includes a limiter bridge which is fixed or abuts on said bridge to immobilise and confine a head of said limiter piston within the limit of said travel.
