Excellent idea if you want to switch on a garage light from inside the house up to 100 foot away.
You can fit two for a 2 way light which will allow you to switch on or off in the house or garage.
Another recent idea.In the domestic house wiring business,it means you can wire all the lighting with no chasing out the plaster.
They are supplied with a receiver but sometimes this is extra.I notice they are now on ebay for around 20 to 30 pounds but most wholesalers will have some.
Just think,put up an outside light on the garage with just a L and N plus the small receiver.Put the switch anywhere in the house with no wiring connection at all.
