Abstract

PURPOSE:To facilitate the exchanging work of the printed circuit boards, by forming a consecutive signal route with the wiring between a conductor pattern on a printed circuit board and a connector of the printed circuit boards. CONSTITUTION:When a fault arises to a printed circuit board 2 and either one of the boards 2 is pulled out of a storing case 1, the closed circuits so far formed with a contact between the contact plug pattern of the board 2 and a contact and connected in series to a terminal 4 of each terminal 3 by electric wires 6 are opened. As a result, the energizing of a relay 7 is released to open relay auxiliary contacts 7a and 7b. Thus a control circuit 9 turns on a fault display device 10. When the repaired board 2 is set again to the original connector 3, a series connection is secured between the contact plug pattern of each board 2 and a contact. Thus the original state is reset. In this moment, a push-button switch 8 is pushed, the relay 7 is energized to close the contacts 7a and 7b. Thus a holding circuit is formed, and the device 10 discontinues its lighting to be reset to the original state of operation.
