The invention provides a control box for selectively delivering orders to receivers (), the control box comprising: 1812. A control box for selectively delivering orders to receivers ( , ) , the control box comprising:{'b': 14', '24, 'a shaft () mounted to turn about an axis of rotation (X), while being capable of sliding along said axis (X) between a rest position towards which it is urged by return means (), and an active position;'}{'b': 16', '11', '14', '14, 'order delivery means (, ) co-operating with the shaft () to deliver orders as a function of the angular position of the shaft ();'}{'b': '15', 'rotary drive means () for causing the shaft to turn; and'}{'b': 23', '27', '28', '27', '28', '15, 'safety actuation means () for causing the shaft to slide from the rest position in which anti-rotation means (, ) prevent the shaft from turning to the active position in which the anti-rotation means (, ) leave the shaft free to turn under drive from the rotary drive means ().'}22728271428282714282714. A control box according to claim 1 , wherein the anti-rotation means ( claim 1 , ) comprise longitudinal grooves () formed in a portion of the shaft () and co-operating with a stationary finger () of the control box so that the finger () is engaged in one of the grooves () when the shaft () is in the rest position and the finger () is disengaged from the grooves () when the shaft () is in the active position.3412714. A control box according to claim 2 , also including at least one retractable finger () adapted to penetrate selectively into one of the grooves () in order to prevent the shaft () from turning.44140. A control box according to claim 3 , wherein the retractable finger () is a moving portion of an electromechanical solenoid actuator ().53637381414. A control box according to claim 1 , further including detector means ( claim 1 , claim 1 , ) adapted to co-operate with the shaft () in order to detect whether the shaft () is in the rest position or in the active ...
