1. A switch with several crosspoints layers, comprised of a plurality of first layers of parallel wires oriented in a first direction and a plurality of second layers of parallel wires oriented in a direction perpendicular to the first layers, the first and second layers being piled up one upon the other in an intercalated manner to form a pile-up, each layer of wires being supported by a frame made of insulating material, a crosspoint being constituted by two wires located in two neighboring layers and a conductor surface of a plug, the height of the conductor surface being sufficient to electrically connect a segment of the wire of the upper layer to a segment of the perpendicular wire of the lower layer, characterized in that each first layer is constituted by a plurality of row wires of uneven rank (H1.1, H1.2, H1.3) and a plurality of row wires of even rank (H2.1, H2.2), each second layer being constituted by a plurality of column wires of uneven ranks (V1.1, V1.2, V1.3) and a plurality of column wires of even ranks (V2.1, V2.2), the row wires and the column wires of uneven ranks forming a first matrix and the row wires and the column wires of even ranks forming a second matrix, first crosspoints being formed by row and column wires in the first matrix, conductor surfaces of first plugs (F) which are wedged between said row and column wires of the first matrix, and row and column wires of similar rank in the second matrix, second crosspoints being constituted by row and column wires in the second matrix and conductor surfaces of second plugs (F') which are wedged between said row and column wires of the second matrix, and row and column wires of upper rank in the first matrix, the first and second plugs (F, F') having a larger diameter than the side of the meshes of the wire layers, each plug conductor surface comprising a first and a second contact surfaces galvanically connected together, the angular positions of the first and second contact surfaces being shifted by 90 degrees and their axial distances being equal to those of two adjacent layers, the switch having also control means capable to rotate the plug heads by quarter of a rotation in one direction or the other. |
