PURPOSE:To ensure the degree of freedom of a wire with less memory number by providing a selector replacing wires mutually between plural wires and a switching means. CONSTITUTION:When the switch is applied to 4X4 wires, selectors 32A-32D, 33A-33D, 34A-34D and 35A-35D in 2 bits each to replace wires mutually are provided respectively between a switching means 20 with a memory and 4 wires 12-1-4, 13-1-4, 14-1-4, 15-1-4, as to wires coming from each direction to reduce less number of switches for the switching means 20 with a memory. Thus, the degree of freedom of wires nearly the same as that of a conventional switch is ensured without increasing the memory number. |
