AVT2405 A

Audio switches are very 'graceful' electronic circuits. They allow you to control your electrical equipment in a spectacular way. The sound signals are usually clapping in hands, whistling, etc. After each sound the system changes its state to the opposite - it acts as a bistable switch. When mounting it in a lighting installation, you can turn on and off the light by clapping.
The above kit has one valuable feature - it uses a system that prevents triggering by single, accidental sounds. The change of state is triggered by a double clap. This significantly increases the functionality of the system.

The device is especially recommended for anyone who wants to remotely (sound) control any device
