COMMUTATOR WITH SEVERAL LAYERS OF THE CROSSING POINTS ABSTRACT OF THE DISCLOSURE A matrix-type switch having several layers of crosspoints for telephone distribution systems, having an improved structural arrangement for removal or replacement in the distribution system. The switch has several layers of crosspoints, composed of several first layers of parallel wires oriented in a first direction and of several second layers of wires oriented in a direction perpendicular to the first layers. The first and the second layers are interposed, each layer of wires being carried by a grid of insulating material. A crosspoint is constituted by two superposed adjacent meshes and a conductor surface of a plug, the height of the conductor surface being sufficient to electrically connect the segment of wire of the upper mesh to the wire segment of the lower mesh. Each plug conductor surface occupies an angular sector of the order of 180°, and is comprised of means to cause the plugs to rotate by one quarter of a rotation in one-direction or in the other.
