Sound Activated Control Switch Kit
Classified as a remote controlled circuit, this product uses an audio signal (hand clap or voice, etc) to activate the on/off function of the switch. A sensitivity/volume controlled microphone picks up the audio signal activating a relay which in turn generates an electrical signal to the switch. This kit may be assembled without soldering on any Global Specialties trainer or breadboard (not included), or by soldering to the included PCB. Parts and assembly instructions included.
