Abstract
A switch system for interconnecting a plurality of balanced line inputs with a plurality of balanced line outputs is disclosed. The lines are crossed in a matrix with a pair of rotatable switch means mounted at each crosspoint. Each pair of the switch means provides straight through connections for the input and output lines while in a first position, and a cross connection at the matrix point while in a second position. The switch means provides identical path lengths for each side of the balanced line before and after switching. The switch system also includes means for grounding the unused contacts and the inactive line sections remaining in the matrix after an interconnection has been made. The matrix is formed of a plurality of interchangeable modules that allow quick and convenient expansion of the matrix when needed.
