Abstract

L'invention concerne un dispositif de commutation destiné à connecter entre elles des lignes de transmission. Ce dispositif comporte une matrice de points de croisement de type << hard reed >> à trois enroulements. Grâce à l'utilisation d'un relais temporisé, la commande est simplifiée puisqu'une impulsion de ligne et une impulsion de commande de colonne suffisent. L'invention s'applique à tout central téléphonique spatial.
