ABSTRACT:
A cross point switching matrix utilizing remanent reed switches includes an array of coil forms mounted on a magnetically permeable shunt plate. Electromagnetic coils are wound around the coil forms in alternating directions and one or more remanent reed switches are contained in each coil. Magnetically permeable coupler plates are mounted on opposite sides of the shunt plates and serve to complete a magnetic path between the ends of each reed switch and the shunt plate through the other reed switches. When two or more reed switches are mounted in each coil, the switches are disposed in a straight line aligned at a 45.degree. angle to the coordinates of the matrix to permit electrical connections to be readily made to the reed switches utilizing straight conductors.
