<P>PROBLEM TO BE SOLVED: To prevent failure of a circuit due to incorrect combination by making a product, e.g. a lighting fixture, to be assembled in correct combination even when the components, e.g. a power supply and a load device, do not come into direct contact with each other. <P>SOLUTION: Printed wiring boards 140, 240 are used in common in two or more kinds of electric circuits. Connectors are mounted on connector mounting parts 150, 250. The connector has a plurality of terminals. A plurality of terminal connection conductor patterns (print wiring 141-143, 241-243) are connected electrically with the plurality of terminals of the connector, respectively. Electric circuits (power supply circuit, load circuit) are configured by mounting the elements on the printed wiring boards 140, 240. Connection select sections 160, 260 can electrically connect the electric circuits and the plurality of terminal connection conductor patterns, respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
