摘　　要：提出了一种新型的触摸开关,通过手指对可见光的反射,识别触摸动作。由于电路设计中人体的触摸动作是通过对可见光的测量,达到人体与电路的高度隔离,具有安全、可见等优点。这种触摸开关可广泛应用于各种需要重点防护人体触电的使用场合,对智能开关的发展有推动作用。This paper presents a novel touch switch which can identify touch action through the reflection of the fingers on the visible light. Because the human touch action is based on visible light measurements in the design of circuit and the high isolation between the human body and circuit is reached, this touch switch has advantages of safety and visibility. It finds wide application in the field of human electric shock protection and promotes the development of intelligence switchs.
