A system for detecting the state of a gear box. Sliding gear selector rods control gear shift forks, and carry notches into which bars may fall. Each of such bars actuates an electrical device for emitting a binary bit. All of the binary bits together form a coded element the reading of which is made with reference to a binary standard to determine the position of the selector rods, which in turn determines the gear ratio or state of the gear box. |
