Sound Activated Switch

Easily adjustable!
This ultra-sensitive switch responds to a whisper or a loud clap. You can easily set the sound sensitivity to which the switch will respond. In the timed mode, you can adjust the length of time the switch will stay on after the initial activation (1-120 seconds). In the latch mode, the first sound will activate a switch closure and the second will disable it. In the momentary mode, the circuit is closed for the duration of sound detection.

Size: 4½"L x 2¼"W x 1¼"H. Requires 1 9-V Battery
