Abstract
La présente invention concerne un interrupteur crépusculaire. Interrupteur caractérisé en ce qu'il est essentiellement constitué par une cellule photorésistante insérée dans un pont diviseur dont les variations de tension en fonction de l'éclairement commandent un circuit intégré standard comprenant quatre portes NON-ET qui attaquent, par l'intermédiaire d'un transistor, un triac commandant le circuit d'éclairage. L'invention est plus particulièrement applicable à la commande de circuits électriques d'éclairage.
