摘要： The encoder has a fixed part (20), a movable part (30) and contactors (32, 34, 36) positioned against an electrical conductor (21). Each of under-tracks (22, 24, 26) has segments. The segments of a same under-track are separated from each other by segments of another under-track, so that the conductor presents an alternation of segments disposed on the same circumference. The contactors belong to the movable part (30) and the conductor belongs to the fixed part (20) or inversely. An independent claim is also included for a control board for an air-conditioning and/or heating, ventilation apparatus of a motor vehicle.
