Abstract: A multilayer cross point matrix switch is composed of orthigonally arranged first and second layers of spaced parallel conductors mounted on insulating guides having window arrays for placement of plugs to interconnect discrete first and second conductors of different layers at a given crosspoint. The plugs contain conductor surfaces occupying an angular sector of approximately 180 degrees. The crosspoint switches are opened or closed by one quarter of a rotation of the plug in one direction or another direction. The plugs are selectively rotated by selection bars having flexible teeth engaging a cresent-shaped head on each plug. Several types of actuating mechanisms for operating the cross-point switches are disclosed.
