How to Make a Touch Switch – Basic Electronics Projects – Breadboard Circuits

This video shows you how to make a simple touch sensor switch on a breadboard using transistors. This circuit can be coupled with a latch and a relay to operate electronic appliances with the touch of a finger.
The components you need to build this circuit are:
* 2 BC547 transistors (or any other npn transistor)
* Resistors: 270 Ohm, 100 KOhm
* LED
* Breadboard Connectors
* Breadboard
* 6V Power Supply
