<p>PURPOSE:To make it possible to selectively change connection between wiring and terminal devices securely and easily by inserting connecting pins into a plurality of holes in a plurality of board plates and connecting predetermined connecting parts of each board plate electrically. CONSTITUTION:A plurality of board plates 15, 16... having a plurality of connecting parts 12-14 where wiring changing devices are installed in parallel and a plurality of holes 11 provided on each connecting part 12-14 and disposed in such a way that the connecting parts 12-14 cross each other, and connecting pins 10 to be inserted into the holes 11, are provided. By inserting the connecting pins 10 into the holes 11, predetermined connecting parts 12-14 of each board plate 15, 16... are electrically connected. Connection between wiring 20 and a terminal device 19 can thus be selectively changed securely and easily in a simple structure.</p> |
