摘要： A switching matrix with threshold value switches connected between the junctions of row and column lines, the threshold value switches being responsive to the temporary application of a sufficiently high operating potential to the associated row and column lines to close or become conductive. Individual preresistance means are connected to the row and column lines which have a small value of resistance compared to that of the threshold value switches in blocked or open condition. Control potentials are applied over the threshold value switches in blocked condition to further threshold value switches. Each of the latter are connected to at least one of a row and column line not receiving the operating potential to decrease the effect of the operating potential thereon to an extent such that the further threshold value switches cannot close.
