The inverter R is inverted through the resistors R 1 and R 2 , and the diodes D 1 and D 2 are resistors R 3 and R through the capacitor C 3 at the output terminal of the inverter 2. 4 ) and a shaping circuit 3 composed of a condenser C 4 and C 5 , which is connected to the output terminal thereof via the inverter 4 to the T-flip flop 5, and at the output side thereof a resistor ( R 6 ) and an OFF state detector 6 composed of a lamp (LED) and an ON state detector 7 composed of a resistor (R 7 ) and a photocoupler (PC) are connected to each other.

이와 같이 구성된 본 고안은 터체센서(1)를 도체 또는 부도체에 접촉시켜 인체가 도체 또는 부도체에 접촉하여 직접 또는 간접적으로 터치센서(1)에 접촉하게 되더라도 가변용량(C1)(C2)에 따라 그 감도가 조절되어 터체선서(1)에 1회 터치하는 순간맏 인버터(2)의 출력이 “LOW”상태로 나타난 콘덴서(C3)를 통하여 샤아핑회로(3)에 입력되어 터치센서(1)에 인체가 1회 접촉함에 따라 접촉시간에 관계없이 폭이 좁은 신호의 미분파가 발생되고 이 미분신호가 인버터(4)를 통하여 T-플립플롭(5)에 입력되게 되므로서 T-플립플롭(5)은 각 출력단(Q)()에 고호로 출력을 나타나게 하여 출력신호()가 “HIGH”일때에는 저항(R6)과 램프(LED1)가 동작하여 부하(8)가 OFF 된 상태를 표시하게 되여, 출력신호()가 “HIGH”일 때에는 저항(R7)과 포토커플러(PC)의 LED2를 동작시킴으로서 포토커플러(PC)가 동작하고 이에 따라 포토커플러(PC)의 cdS를 통한 전압이 TRIAC을 동작시켜 줌으로서 부하(8)가 ON 상태로 유지하게 되며, 이와 같이 부하(8)의 ON, OFF가 터치센서(1)에 인체가 접촉되는 순간마다 교호로 동작하게 되는 것이다.The present invention configured as described above has a variable capacitance (C 1 ) (C 2 ) even if the human body is in direct or indirect contact with the touch sensor (1) by contacting the terrestrial sensor (1) with a conductor or a non-conductor. As a result, the sensitivity is adjusted and the output of the first inverter 2 is inputted to the shaping circuit 3 through the capacitor C 3 in the state of “LOW” when the touch is made once. When the human body touches 1) once, a differential wave of a narrow signal is generated regardless of the contact time, and the differential signal is inputted to the T-flop flop 5 through the inverter 4, thereby causing a T-flip. The flops (5) are each output stage (Q) ( Output signal with ) Is "HIGH", the resistance (R 6 ) and the lamp (LED 1 ) are operated to indicate the state that the load (8) is OFF, the output signal ( ) Is “HIGH”, the photocoupler (PC) operates by operating LED 2 of resistor (R 7 ) and photocoupler (PC), and the voltage through cdS of photocoupler (PC) operates TRIAC. As a result, the load 8 is kept in the ON state, and thus the ON and OFF of the load 8 are alternately operated every time the human body contacts the touch sensor 1.

한편 본 고안은 또한 자체전력 소모가 많은 트랜지스터를 사용하지 않고 AC 입력에 부하(8)과 병렬로 콘덴서(C6),(C7)과 순방향 다이오드(D3)(D4) 및 정전압 다이오드(ED1)으로 구성된 DC 전원 공급회로(9)를 구성하여 각 회로를 동작시켜 줌으로서 전력소모가 무시될 정도로 작을뿐만 아니라 콘덴서(C6) 및 (C7)에 의하여 AC 입력의 극성에 관계없이 신속하게 동작하므로서 그 동작 신뢰성이 향상되며, 또한 터치입력을 검출하는 터치센서(1) 부분에는 입력 임피던스가 대단히 높으므로서 직접 터치뿐만 아니라 세라믹과 같은 절연체로 구성된 용기나 물체에 부착시켜 사용하더라도 정확히 동작할 수 있는 고감도의 터치스위치를 염가로 제공할 수 있는 매우 실용적인 고안인 것이다.On the other hand, the present invention also eliminates the need for self-powered transistors and in parallel with the load (8) at the AC input, the capacitor (C 6 ), (C 7 ) and the forward diode (D 3 ) (D 4 ) and constant voltage diode ( The DC power supply circuit 9 composed of ED 1 ) is operated to operate each circuit so that the power consumption is negligibly small, and regardless of the polarity of the AC input by the capacitors C 6 and C 7 . The operation reliability is improved by operating quickly, and the touch sensor (1) part that detects touch input has a very high input impedance, and it is precisely used even if it is directly attached to a container or an object made of an insulator such as ceramic. It is a very practical design that can provide a high-sensitivity touch switch that can operate at a low cost.
