In this simple Touch lamp switch circuit, we have used timer IC 555 operated as ON and OFF. By using this circuit you can turn ON and OFF a device by simply touching the Touch Plates or metal used as a sensor. If the touch plates are placed at a convenient place, we do not require moving from our location to turn them on and off the device. The important feature of this circuit is that we will not get any electrical shock which we sometimes get while using normal switches.

The design of the touch lamp Switch circuit is very simple. We have connected pins no 8 and 4 of the 555 with the VCC supply. Pin 1 is connected to GND and 5V respectively. Pin 2 of the IC is pulled HIGH using a 3.3 MΩ Resistor. Pin 6 is pulled LOW using a 1 MΩ Resistor.
As shown in the diagram two touch plates are connected. In the case of the touch-to-ON plate, one end is connected to pin 2 and the other end is connected to – supply. Similarly, one end of the touch-to-OFF plate is connected to VCC (5v) and the other end is connected to Pin 6.
We can use this simple touch lamp switch to control any home appliance. It is a very efficient and simple touch light switch. Only one thing must keep in mind if you want to control AC appliances then use a suitable relay. it is a magic touch lamp switch for fun or any hobbies.
