DESIGN OF CLAP SWITCH DEVICE

This project proposal is of a clap switch device. Clap switch is a switch which can switch on/off any electrical circuit by the sound of the clap.

The basic idea of a clap switch is that the electric microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage.

This circuit has been constructed using basic electronic components like resistors, transistors, relay, transformer, capacitors. This circuit will turn „ON‟ light for the first two claps. For the next two claps, the light turns OFF. This circuit works with 12V voltage. T

herefore a step-down transformer is employed. The primary application involves an elderly or mobility-impaired person. It is generally used for a light, television, radio, or similar electronic device that the person will want to turn on/off from bed. The major disadvantage is that it is generally cumbersome to have to clap one’s hands to turn something ON or OFF and it’s generally seen as simpler for most use cases to use a traditional light switch.
