This is a relay controlled by the sound: clapping puts the relay into the working position, another rest position. The relay contacts can switch electrical devices up to 2000VA.
This circuit is powered by a 9 volt battery which delivers current in its relay resistance lorqu'il is in working position. Under heavy utilsation, provide AC power for the battery runs out quickly.

Drill the circuit board 0.8mm, set up the components in the orientation with the correct polarity (diode, one, transistors and capacitor)
The electret microphone is wired outside the circuit for psitionner the facade if you use this assembly in a box.
Supply the assembly with a 9V battery and actuate the switch. Snapping hands to control the relay. so shall control loads 230V, output cable should be in compliance with the electrical regulations.
