PROBLEM TO BE SOLVED: To provide a switchboard, capable of coping with miniaturization by reducing dimensions in three directions of a relay control part together. SOLUTION: A switchboard 1 consists of a driving circuit part 13 supplying power to a load, and a control circuit part 16 having a relay control part containing a plurality of relays for controlling the driving circuit part 13. The relay control part consists of a relay module 3 in which a plurality of relays 6a, 6b, 6c, 6d and a plurality of connectors 5a, 5b, 5c for repeating electric signals operating the relays are arranged along the direction of operation of relay contacts, and a module is constituted by using a printed wiring board 7. Thereby dimensions of the width, the height and the thickness of the module 3 are reduced, and miniaturization is realized. |
