How do you switch on a light bulb by clapping?

In: Electrical Wiring [Edit categories]

Answer:

You have to install a device known as a "clapper" into your receptacle outlet. Plug your lamp into this device. It is sound activated. When you clap your hands the device senses the frequency of the clap and activated its internal circuitry. This closes a relay that supplies voltage to the lamp and it turns on.
