Touch Switch Circuit Diagram

Usually, we use the switch to turn on and off any circuit or any device. But it is possible to turn on and off of any device by just simply touching the surface? Yes, it is possible by using a couple of transistors and few more electronic components we can easily create this type of circuit. Through this circuit, we can easily on any divide by the simplest tapping on the phone and simply of the device by just simply tapping on the off pads. What is a touch switch? It is a simple type of switch which turns on and off the device by just simply touching the pads for connection. These are the simple sweets that we can use in our devices to make them modern and comfortable. Generally for this type of circuit, we use an IC but here we are creating these circuits by using a couple of transistors and few more components. Component Needed; 1) 3x BC547 and a BC557 Transistor 2) 10k, 4.7M, 470k, 4.7k, 330R Resistance 3) Led
