Turn on and turn off your electrical devices using touch switch, so you can “play” your electronic devices more fun.. 🙂 . Touch switch don’t need mechanical part, so they will not worn out due to mechanical contact. Touch switches can be used in places where regular switches would not last, such as wet or very dusty areas. You just need to add some relay to switch your devices which require high voltage supply.
Here the touch switch schematic diagram:
