Abstract of the Disclosure A system for switching signals travelling between a first set of multicontact ports and a second set of multicontact ports, in which the signals at the contacts of each of the first ports are sampled by a parallel-to-serial multiplexer to form a corresponding single serial multiplexed signal. Each such serial multiplexed signal is applied to a matrix switch of the type having a switching device at each cross-point, and each of the output signals from the matrix switch is supplied to a serial-to- parallel demultiplexer. Each such demultiplexer. supplies its reconstructed separate parallel signals to its associated port in the second set of ports. By controlling the conduction status of the switching devices in the matrix, the desired connection of each of the first set of ports to the desired one of the second set of ports is accomplished, with many fewer switching devices than would otherwise be required.
