How to Make Touch Switch at Home. Home made touch switch on off

In this video, I have shown how to make a simple Home Made Touch Switch using basic electronic components.
Touch switches available in the market are often expensive, but we can easily build one at home with simple parts like a transistor, relay, and TTP223 touch sensor.

✅ Components used in this project:
Transistor
Resistors
Relay / Relay Module
Diode
Capacitor
TTP223 Touch Sensor Module
LED Bulb / Light

⚡ Working Principle:
When we touch the TTP223 sensor (or metal touch plate), a very small electrical signal activates the transistor.
This, in turn, drives the relay and allows us to control a light or any other AC/DC load.
The diode and capacitor provide stability and protection for the circuit.
