<p>PROBLEM TO BE SOLVED: To provide a structure capable of sharing parts and rationalize manufacture and maintenance by providing a breaker mounting part matching mounting pitches of a plurality of breakers. SOLUTION: A case 9 formed of an insulation material is provided with a plurality of hole parts 15 so that plural sizes and types of mounting pitch breakers 8 can be mounted, and is structured so as to sandwich and fix the breakers 8 and cases 9 by a metallic mounting part 10 matching each breaker 8. Here, the breaker 8 is provided with input and output terminals 7 on the top and bottom thereof, respectively, and an upper side input and output terminals is employed as a power input terminal, and is connected so that power is supplied to the breakers 8 from a trunk breaker via a metal bar and a power input terminal. On the other hand, a lead wire 6 is connected to a lower side input and output terminal, and this lead wire 6 is connected to a dimming circuit mounted and disposed on a printed wiring board 11. Thereby, even if a breaker is changed according to required specifications, a mounting part 10 can be assembled by only replacing it.</p> |
