Abstract
본 발명은 적외선 발광 LED와 수광 LED를 이용한 접촉스위치에 관한 것으로, 적외선 발광 LED에 전류신호가 인가되면 적외선이 발생되어 적외선 투과판을 통해 투과되는데 이용자가 적외선 투과관을 접촉하는 경우 적외선 수광 LED에 설정된 임계량 이상의 적외선이 입력되어 전류신호가 발생되므로써, 접촉스위치가 작동되므로 생체저항을 이용한 종래의 접촉스위치에 비해 이용자의 접촉상태를 보다 정확하게 감지할 수 있도록 한 것이다.The present invention relates to a contact switch using an infrared light emitting LED and a light receiving LED. When a current signal is applied to the infrared light emitting LED, infrared light is generated and transmitted through the infrared transmission plate. Since the touch switch is operated by the input of infrared rays above a predetermined threshold amount, and the current signal is generated, the contact state of the user can be detected more accurately than the conventional touch switch using the bioresistance.
