ABSTRACT:
A selector is typically arranged to control adjustment of a motor vehicle headlamp between a plurality of discrete, stable positions. It includes a control member arranged to occupy a number of discrete stable positions, a switching member operated by the control member, a voltage generator for giving voltage signals and having two supply inputs, a control output terminal for operating an actuator for the headlamp, and at least one coded network of resistors and electrical contact strips.
The output terminal is connected to each supply input through at least one resistor, the coded network comprising at least one collecting strip connected to the output terminal, together with a secondary contact strip, also connected to the output terminal, and a primary contact strip connected to one of the supply inputs. The various contact strips are so arranged that the switching member cooperates with the collecting strip in all of the positions, with the primary contact strip in a smaller number of positions, and with the secondary contact strip in an even smaller number of positions.
