Abstract
L'invention concerne les dispositifs de commutation. Un point de commutation pour un réseau de commutation à semiconducteurs est constitué par deux transistors bipolaires complémentaires 100, 101. Chaque transistor est branché en parallèle sur un circuit de commande protecteur, 102, 103, qui assure une protection contre les surtensions et les tensions inverses, ainsi qu'un blocage effectif de chaque transistor lorsque le point de commutation est à l'état ouvert. Application aux autocommutateurs téléphoniques.
