When you turn the wireless switch remote on and off, it sends a signal to the receiver, telling it to turn the power on or off. It's that simple. Each switch and receiver have own code and will not interfere each other. The Handy Switch works with lamps, fans or other devices that plug into the wall. Handy Switch range is approximately 60 feet, and the radio frequency it uses will penetrate thru walls.
The handy switch will light up when it turn on, which is different from old one.
