Simple Touch Switch

TOUCH SWITCH USING TRANSISTOR

How to make simple touch switch circuit using one transistor. This is a mini project which requires minimum components

A touch switch is a type of switch that only has to be touched by an object to operate. 

It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals.

A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.

Components required:

*BC 547 transistor

*Wires

*Breadboard

*LED

*1k ohm resistor

*9v battery
