Abstract
1. A gear-change control device for a gear box comprising at least one block of sliding gears (1), the displacement of which is obtained by means of a rod or fork (3) actuated by a servo drive (8) driving a threaded shaft (7) on which is mounted a nut (6) whose displacements are simultaneously driving the fork (3) and a control member such as a finger, a lug or a notch (10) which actuates switches (11-14) controlling the servo drive (8), characterized in that the servo drive is also driving a rotary cam (19) having a single boss (20) cooperating with a switch (21) connected in parallel with the switches (11-14) placed on the control circuit of the servo drive (8).
