To use these wireless light switch kits, the relay is simply wired behind the light fixture that it will be controlling. The relay receives a signal from the rocker switch that it is programmed to when the switch is pressed. There is a small amount of energy created when the rocker switch is pressed so it is a self powered system that requires no batteries. Using this kind of technology saves time because you don't need to fish wire or knock through walls.
These switch kits can be used in many different configurations. If you wish to control more lights with one switch, you can add additional relays. Extra relays can be purchased from our amazon store (item B01NAUR0EQ). If you wish to control a light from multiple locations, you can add additional switches. Extra switches can be purchased from our amazon store (item B01ILQ7PNO)
