PURPOSE:To attain ease of changeover of ON/OFF/ dimmer of a lighting device, power saving and ease of alteration of a control series by attaining the same load control even if any of plural switches is operated. CONSTITUTION:When any of the operation switches 5-1-5-m is operated, a supervisory terminal device 4-x to which the operation switch 5-x is connected transmits switch information while adding the own address to a transmission line 2. A main operating panel 1 forms control information based on the switch information and transmits it to the transmission line 2 together with a control terminal device 3-y address. Control terminal devices 3-1-3-n control a load according to the control information transmitted together with the own address thereby controlling a load of a load control system with the operation of the operation switch 5-x. |
