Abstract
A method for fabricating a matrix switch board used for connecting and disconnecting a switching-system line and a subscriber line. The matrix switch board is formed to include a board made of an insulating material, first and second wiring patterns respectively formed on front and back sides of the board so as to cross each other, and through holes provided at cross points of the first and second wiring patterns. A connection pin inserted into at least one of the through holes, electrically connects at least one of the first wiring patterns on the front side and at least one of the second wiring patterns on the back side.
