Sound Activated Wired Switch

The ultra-sensitive Sound Activated Switch responds to a whisper or a loud clap and is great for people with very limited mobility. Choose between three modes: Timed Mode – adjust the switch to remain on for 1-120 seconds post-activation. On/Off Mode – one sound turns on the device and another sound turns it off. Momentary Mode – device activation is dependent on the duration of sound detection. The switch can also be adjusted for sound sensitivity. Size: 4½"L x 2¼"W x 1"H. Requires One 9-Volt Battery (not included)
