Abstract: 본 발명은 조명등. 씰링팬(Ceiling Fan)등의 전기기기를 제어함에 있어, 기 설치되어 있는 스위치 배선을 이용하는 것에 관한 것으로서, 
     벽에 부착된 전원 스위치기의 구성은 메인 스위치와 코일을 직렬로 연결한 후 상기 코일과 병렬로 터치 스위치 2 개를 구성하되 그 하나는 직접 연결하고 그 다른 하나는 다이오드와 직렬로 연결하여 구성해서 상기 2 개의 터치 스위치로 천정의 전기기기를 사용자가 원하는 대로 제어하는 것이다.  천정의 조명등, 씰링팬등의 전기기기에는 내부에 펄스 신호 생성부, 신호 검출부, 마이콤 제어부, 구동 회로부 (Drive Circuit Part), 전원부로 구성된 제어기를 두어 상기 스위치기로 부터의 스위치 신호를 스위치 배선을 통하여 정확히 전달받아 스위치 신호의 종류(2종)와 그 눌러진 회수를 정확히 판단해서 상기 전기기기를 사용자가 원하는 대로 제어하는 것이다.  이상과 같은 본 발명은 기존의 스위치 배선을 그대로 사용하고 그 구성이 간단하기 때문에 설치 및 사용이 편리하고 가격 경쟁력을 상승시키는 효과를 제공하게 된다.
