Abstract
A relay matrix which constitutes an array of switches providing connection points between a set of 'horizontal' inputs and a set of 'vertical' outputs, has n relays per column disposed in p columns. Each relay column is associated with a register which fulfills the functions of controlling and storing the state of the relays of the column. The invention can be applied to switching systems and in particular to automatic telecommunication exchanges.
