Highly sensitive sound activated latching relay switch or clap switch. Can be used to control external apparatus ON and OFF from a distance using sound e.g. it will respond to voice, hand clapping, whistling, etc.
Each time it receives a trigger signal the relay will switch state (latching from either Off to On or On to Off) and will stay in this state until it receives another sound. The sound level trigger sensitivity is adjustable.
The output relay has NO and NC connection options and is rated to switch up to 230Vac/28Vdc at 5 Amps maximum current.
Suitable for use in alarm systems, control systems for the disabled and many other applications.Specifications
