Abstract

L'invention concerne un circuit de commande destiné à être utilisé en liaison avec une résistance ajustable pour produire un premier signal de commande dont l'amplitude est fonction de la valeur de réglage de la résistance et un second signal de commande dont l'amplitude passe d'un premier à un second niveau pour une valeur de réglage prédéterminée de la résistance. Le circuit comprend deux transistors 20 et 21, une résistance ajustable 7, une impédance formée des résistances 26 et 27, une source de courant 28. Le circuit peut notamment être utilisé pour commander l'un de deux appareils, ou un seul appareil ayant deux gammes de fonctionnement différentes.
