Intelligent switch is capacitive touch sensor which senses the touch. This type of switches takes body capacitance as a input in order to turn ON or OFF the devices which is connected to it and also the regulation of it. The devices controlled are bulb, fan, motor and other electronic appliances. Keywords: Capacitive touch sensor, Pulse width modulation (PWM), Light emitting diode (LED), DC gear motor.

2. What is an Intelligent Switch ?
Intelligent switch is capacitive
touch sensor which senses the
touch. This type of switches takes
body capacitance as a input in
order to turn ON or OFF the
devices which is connected to it
and also the regulation of it. The
devices controlled are bulb, fan,
motor and other electronic

3. Why Smart Switch ?
This touch switches are needed in order to overcome
the disadvantages of mechanical switches
like wear and tear, limited operations, sparks etc.
Used to replace the mechanical switches thus providing
high reliability, shock proof, trendy looks etc.
It reduces the power consumption and improves the quality of life.
