Magnetically controlled switching device

A magnetically controlled switching device comprising:

• a magnetic shunt plate with insulated terminals arrayed along peripheral portions thereof,
• a plurality of coil forms located to define crosspoints of a matrix corresponding to rows and columns along X and Y coordinate directions, respectively, on each of the top and bottom surfaces of said shunt plate,
• an X coil control line extending along each said row on each said surface of said shunt plate and being wound on each of said coil forms in the respective row in an alternately reversed manner, both ends of each said X coil control line being connected to corresponding ones of said terminals located on said shunt plate near the ends of said rows of coil forms,
• a Y coil control line extending along each said column on each said surface of said shunt plate and being wound on each of said coil forms in the respective column in an alternately reversed manner, both ends of each said Y coil control line being connected to corresponding ones of said terminals located near the ends of said columns in the direction Y,
• reed switches accommodated in each of said coil forms, the contact points of said reed switches corresponding to the plane of said shunt plate,
• a respective connection wire extending along each said row and column on each of said shunt plate to connect in common the respective terminals of said reed switches of each said row and column of each surface of said shunt plate,
• a relay terminal plate located parallel to said Y coordinate direction between two of said columns of said coil forms, said relay terminal plate comprising a pair of insulated coil relay terminals corresponding to each one of said rows of coil forms, said relay terminal plate dividing said matrix of coil forms on both surfaces of said shunt plate into two groups,
• each said X coil control line on the top surface of said shunt plate being connected by the respective coil relay terminal of said relay terminal plate to the respective X coil control line on the bottom surface that is wound on the coil forms at identical crosspoints of said matrix, and said X coil control lines in each said row being wound in the same respective direction on the two coil forms adjacent to said relay terminal plate in each respective row, said respective winding direction alternating along said relay terminal plate,
• said X coil control lines being cut between said pairs of said relay terminals so as not to connect in common the two portions of each said row divided by said relay terminal plate, and
• each said connecting wire extending along the respective row in the X direction being cut at the portion corresponding to said relay terminal plate to form two independent matrices on said magnetic shunt plate.
