Abstract
The invention discloses a touch switch control circuit of a fading type delay lamp. The touch switch control circuit comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a first capacitor, a second capacitor, a first triode, a second triode, a field-effect transistor, a thyristor, a voltage stabilizing diode, a touch electrode plate, a bridge rectifier circuit and the lamp. According to the touch switch control circuit of the fading type delay lamp, when the lamp needs to be turned on, the circuit can be switched on just by touching the touch electrode plate, and then the lamp is turned on immediately; after a certain time delay, light of the lamp becomes dimming until the light goes out. A touch switch is only provided with two external lead wires and can be used for replacing a common lamp switch without changing original wire arrangement; the delay time can be changed by adjusting the resistance value of the sixth resistor. The touch switch control circuit is simple in structure and convenient to replace and has the popularization and use value.
