Abstract

Thermostat électronique comprenant un interrupteur électronique et des moyens de commande de l'électrode de commande de celui-ci à alimentation continue et amplificateur différentiel aux deux entrées duquel sont appliquées les tensions de point milieu de deux ponts diviseurs en parallèle dans l'alimentation continue, l'un de ces ponts incluant une thermistance, caractérisé en ce que l'interrupteur électronique alimente une résistance de chauffage d'un relais à bilame à rupture brusque assurant la commutation du courant de charge, et en ce que la charge est en série d'une part avec l'interrupteur électronique et la resistance de chauffage, et d'autre part avec les contacts du relais à bilame disposés en parallèle aux éléments précédents.
