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