Abstract
Abstract An apparatus for interconnecting a plurality of switch modules is disclosed. The interconnecting apparatus comprises a planar array of switches. Each of the switches has four switching leads, two lying in the plane of the array and one extending perpendicular to the plane on either side thereof. A programmable control enables the establishment of a switched connection between any two of the four leads comprising a particular switch. Switch modules lying on either side of the plane array may be interconnected in this manner.
