Abstract
Dispositif de commande pour l'alimentation en courant continu de lampes d'éclairage pour des instruments montés sur le tableau de bord de véhicules automobiles. Ces moyens de commande comprennent des premiers moyens agencés de façon à produire un signal de commande réglable, de puissance relativement faible en comparaison du signal d'alimentation, et des seconds moyens qui reçoivent ce signal de commande et sont agencés de façon à délivrer aux dispositifs d'éclairage le signal d'alimentation en fonction du signal de commande.Control device for the direct current supply of lighting lamps for instruments mounted on the dashboard of motor vehicles. These control means comprise first means arranged so as to produce an adjustable control signal, of relatively low power compared to the supply signal, and second means which receive this control signal and are arranged so as to deliver to the devices lighting the power signal according to the control signal.
