ABSTRACT:
A redundancy switching system which provides four reserve devices is disclosed which is suitable for use with from eight to twelve channels. The switches in the input switching network of this redundancy system are connected in first and second sections. Each section includes a ring of switches and two switches connected as appendages to the ring. Only as many switches are needed to control the input connection to the redundant devices as there are redundant devices. A similar number of switches are needed to control the output connection of the active devices.
