ARRAYED SWITCH CIRCUITRY SYSTEM AND SWITCHING CIRCUIT

An arrayed switch circuitry includes contact units each of which includes a pad, a first row channel provided with a first switching element, a first column channel connected to the first row channel and provided with a second switching element, a connecting channel connecting the pad to the first row channel or the first column channel, a second row channel connected with the pad through a third switching element and a second column channel connected with the pad through a fourth switching element. The first row channels with the same row position are connected to each other, and the second row channels with the same row position are connected to each other. The first column channels with the same column position are connected to each other, and the second column channels with the same column position are connected to each other.
