Abstract

La présente invention concerne un circuit électronique d'injection de sonnerie pour une ligne téléphonique. Il comporte principalement deux triacs dont le circuit de commande comprend des moyens pour délivrer sur leur gâchette un courant redressé toujours supérieur au courant d'amorçage, ce courant de gâchette étant produit à partir de la tension alternative de sonnerie. Application aux centraux téléphoniques électroniques.
