ABSTRACT:
The present invention relates to a time division, multi-voltage level matrix switching system wherein a minimum number of connecting lines or wires are used between a transmitter and a receiver for actuating a multiplicity of working units such as lights, communication devices, and other types of signalling devices. More particularly, each respective working unit is operatively connected in a matrix configuration, with a plurality of such working units being operatively connected in various normally open circuits within the matrix complex. The matrix complex is controlled by a central switching system that is operatively connected thereto and is adapted to provide at least two different voltage level signals to anyone of the normally open circuits within the matrix complex in order that the circuit will be closed, and a particular working unit therein will be actuated. Of important significance, is that the central switching station is adapted and designed such that two timed voltage level signals can be placed on a single main conductor line in the same time sequence, and wherein the two voltage signals are operative to effectively simultaneously close one circuit having at least one working unit operatively connected therein.
