Touch Sensitive Lamp Circuit

These buttons of course don t work if you have cold hands.
Touch sensitive lamp circuit. By touching this touch dimmer you can increase the light intensity of incandescent lamps in three steps. Collection of touch lamp sensor wiring diagram. By placing two contacts very close together your finger can close the circuit when you touch it.
At the second touch the bulb gives medium light. Tt 6061 is specifically designed for this purpose. Many elevators therefore use buttons that are sensitive to the warmth of the human finger.
The ic used in this transformers touch lamp with delay circuit is a double d flip flip ic 4013 which has 2 flip flop stages built inside it here we make use of one of these stages for our application. An led can be seen connected with this supply which ensures a dim light is always on near the circuit for facilitating quick location of the touch switch pad. Circuit diagram of touch sensitive switch circuit using a transistor the touch probes are connected with 100 k ohm resistor and base pin of 2nd transistor respectively.
Connect the base pin of the 2nd transistor to the emitter pin of the 1st transistor. The motion sensitive lamps you see on people s patios also sense the heat of the human body. Here resistor r1 is the current limiting resistor.
This is a simple touch dimmer circuit made of ic tt6061. When you touch the plate the lamp glows dimly. Resistance the human body being made mostly of water conducts electricity fairly well.
