PURPOSE:To improve operating performance by connecting a push button switch as a dimmer and ON-OFF operating slave unit to a mainframe at a different position from the dimmer mainframe to realize both ON-OFF and dimmer operation. CONSTITUTION:A dimmer mainframe 1 and a slave unit 2 are arranged at separate positions. The operation of one operating member of the mainframe 1 allows the ON-OFF operation or change of supply power to a lighting load 4. As the consistent open contact of a dimmer switch 6 in the mainframe 1 and the consistent open contact 7 of the slave unit 2 as a push button switch are connected in parallel, the ON-OFF and dimmer operation of the load 4 are allowed likewise by operating the operating member of the slave unit 2 at a different position. As a result, both ON-OFF and dimmer operation are allowed by the operation of one push button switch, to improve operating performance. |
