Control box
Abstract:
A control box for selectively delivering orders to receivers (8, 12). The control box comprises a shaft (14) mounted to turn about an axis of rotation (X), while being capable of sliding along the axis (X) between a rest position towards which it is urged by return means (24), and an active position. An order delivery apparatus (16, 11) co-operates with the shaft (14) to deliver orders as a function of the angular position of the shaft (14). A rotary drive (15) causes the shaft to turn. A safety actuator (23) causes the shaft to slide from the rest position in which anti-rotation structure (27, 28) prevents the shaft from turning to the active position in which the anti-rotation structure (27, 28) leave the shaft free to turn under drive from the rotary drive (15).
