PURPOSE:To safely operate a bathroom lighting changeover switch by installing a second control portion which outputs changeover signals of a first lighting and a second lighting by a signal from a first control portion and a lighting changeover switch signal. CONSTITUTION:A first control portion 28 inputs an ON signal of a lighting main switch 2 and a second control portion 29 is insulated from a power source and processes a signal from the first control portion 28, and outputs a changeover signal to a first lighting equipment 26 and a second lighting equipment 27. A bathroom lighting changeover switch 11 is, therefore, insulated from the power source, so that even if any abnormality occurs with the switch 11, there are no possibilities that a leak may occur when a person may touch the switch 11. It is thereby possible to safely operate the bathroom lighting changeover switch 11. |
