ABSTRACT:
A magnetically controlled switching device having a magnetic shunt plate with many terminals arrayed along the peripheral portions thereof, a plurality of coil forms located at the crosspoints of a matrix consisting of X and Y coordinates on a plane surrounded by the terminals on the magnetic shunt plate, an X coil control line wound on each of the coil forms in the row in the X direction in an alternately reversed manner, both ends of the X coil line being connected to corresponding terminals located along the X direction, a Y coil control line wound on each of the coil forms in the column in the Y direction in an alternately reversed manner, both ends of the Y coil control line being connected to corresponding terminals located along the Y direction, reed switches accommodated in each of the coil forms, contact points of the reed switches corresponding to the magnetic shunt plate, and the reed switches being connected to a plurality of matrix crosspoints consisting of multiple connection wires in the directions X and Y, which are arrayed on both the front and back surfaces of the magnetic shunt plate. A relay terminal plate having a plurality of pairs of coil relay terminals is provided at a central portion of the magnetic shunt plate to divide the coil forms into two groups, such that at least two independent matrices are formed on the magnetic shunt plate.
