A drive pedal transmission system contains a potentiometer from which a signal is produced according to the position of the pedal. This potentiometer consists of a conductor plate (1) on which are imprinted slideways (2, 3), one of which (3) consists of a resistance path in which the initial range (3a) and the final range (3c) are formed from highly conductive material and have little or no resistance value. Within the initial and final ranges of the shift path, i.e. before the idling position and after the fully-loaded position, the potentiometer produces a constant signal. Resistors (4a, 4b), tunable by the sensor, hold or modify the signal value. Thus tolerances are not exceeded. The system is simple and inexpensive.
