Clap switch means…!!Clap switch is switch which can switch on/off
any electrical circuit by the sound of the clap

Principle….
Converts the sound signal into electrical energy

Basic Idea on clap switch isBasic idea on clap switch is that the electric
microphone pick up the sound of your claps, coughs, or any sound to switch ON/OFF the circuit

WorkingAudio amplifierSound signal is received by AUDIO
AMPLIFIER . Here the given sound signal is converted
into electrical signal and then amplified by using
transistors.

Flip flop circuit
It consists of two transistors, one for the on position and the other for the off position.
For this reason it is also known as bi-stable multi vibrator.

Circuit amplifier
The outcome of this circuit is Electrical signal.
This electrical signal is very weak so we have use another transistor in this circuit.

ADVANTAGES1. The primary application involves an elderly
or mobility-impaired person.2. We can turn something (e.g. a lamp) on and
off from any location in the room (e.g.while lying in the bed) simply by clapping our
hands.3. Low cost and reliable circuit.4. Complete elimination of man power.5. Energy efficient.

DISADVATAGES1. It is generally cumbersome to have to clap
one’s hands to turn something on or off and it is greatly seen as simpler for most use
cases to use a traditional light switch.2. Unless we use a filter in the circuit , it is not
that advantageous. So that circuit activates only for clap of particular
frequencies and then it becomes accurate.
