Self-Powered Wireless Switch & Receiver Kit - No Batteries Needed, 150+ft RF Range, No WiFi Required - for Ceiling Fans & Lights (Includes 2 Receivers & 1 Double Switch) - White - Perfect for Home Automation & Smart Lighting Control

I used this remote switch to replace a pair of wall switches. The existing switches (two switches ganged in one box) would be inaccessible behind a tall cabinet once we finished moving furniture around. I installed the two remote modules after removing the existing toggle switches from the electrical double-gang box and mounted the double remote “toggle” switch nearby but in a fully accessible location. The electronic switch modules are smaller than the legacy toggle switches, so they fit nicely in the electrical box. The remote modules each have a small red & a green LED which indicates if the switch is in the ON (green) or OFF (red) mode. Although in most installations you probably won’t be able to see these LEDs, they do help in confirming that you’ve wired up everything correctly. Note that in order to install these inside a switch box, you MUST have white (neutral) wires inside the box. If there is no white wire(s) inside the box, the remote module will have to be installed at the fixture instead.The included switches which activate the remote modules use no batteries at all, which is extremely clever and useful. No batteries to replace, as other remote switches have! On this double-gang set, the two toggles are made slimmer so that TWO toggles fit in the space of ONE toggle, which is another huge plus: the double switch unit is exactly the same width as a single standard switch, and a standard “Decora” switch plate could be used instead of the included one, so you install the switch with any switch plate from Home Depot, Lowes, etc. The switch itself is very shallow so if you want you could simply screw the switch & switch plate assembly onto the wall directly (no box needed) or use the enclosed double-sided tape. As the entire switch assembly is so shallow and only sticks out a little from the wall, it looks fine surface mounted.The whole shebang is made in the US, and is of a very high quality. Even the wires are stranded, tinned copper; being so flexible makes it easier to install. Highly recommend this remote switch!
