Abstract
Abstract A signal switching device with a plurality of each of first and second groups of rectangular parallelopiped switching units arranged in X,Y, and Z directions. A plurality of first groups of spaced parallel conductors are disposed in said X direction in respective spaced X-Z planes of said first group units for multiply connecting of break terminals of corresponding switches in said respective first group unit stacks. A plurality of second groups of spaced parallel conductors are disposed in said Y direction in respective Y-Z planes for multiply connecting make terminals of corresponding switches of said second group units in said Y-Z planes. Input signal lines are disposed in parallel and connected to break terminals of said switches in respective first group units in said X-Z planes, while output signal lines are disposed in parallel and selectively connected to make terminals of switches of the second group units in the Y-Z planes, whereby a desired one of the input lines is connectable to a desired one of said output lines.
