You use remote controls to operate your A/V equipment. Now you can enjoy that same ease of use by turning lamps, fans, and radios on and off with a wireless remote control. The On/Off Remote Control sends radio signals through walls, doors, and floors, so you'll be able to turn on an upstairs lamp from your couch or an inside lamp from your car.Just plug the device you want to control into this module and you'll be able to turn it on or off with the included remote control, even if you're not in direct view of the module. The remote works from anywhere within 50 feet. With four selectable channels, you'll be able to use up to four of these devices in your home. Use it to control holiday lights, under-counter lighting, or any plug-in lamp.
