CIRCUIT ARRANGEMENT FOR COUPLING, HOLDING AND RELEASING OF CROSSPOINT RELAYS IN A CONNECTION PATH IN TELECOMMUNICATION SYSTEMS

摘要

A marking and holding circuit for cross-point relays in a plural stage communications switching network. In each stage, the winding of the cross-point relay is held through an individual hold path including its own contacts. The holding potential in successive stages is connected in a back-to-back arrangement to allow selected relays in successive stages to be seized in multiple to complete a path through the network. In the path, the selected relay in each stage is held individually through its own cross-point contacts.
