5.0 out of 5 stars: This Wireless Switch— I’d buy one, … wait … I did !
If you’re fed up walking across a dark room ‘cause the switch is at the other end, or if you just want to add a switch to a light fixture without tearing open your walls, the DEWENWILS Remote Control Switch system is an absolute must. This system delivers genuine wireless control that is powerful, reliable, and incredibly affordable.Reliability and RangeUnlike many “smart” home devices that rely on finicky Wi-Fi networks, this switch uses dedicated Radio Frequency (RF) control, which is its greatest strength.• 100-Foot Wall Penetration: The signal is advertised to work reliably up to 100 feet in open areas and effortlessly passes through walls, doors, and floors. I installed a receiver in my garage ceiling and placed the switch transmitter near the house entry door 50 feet away, and it works perfectly every time.• Zero Wi-Fi or Apps Required: This is a huge win for simplicity. There is no need to bother trying to setup your “Home Assistant,” ( Google / Alexa ) or even download an app, or find an internet connection. It’s simple, dependable control, just press the button, and the light turns on.• Expandable System: The non-interference technology means you can use multiple switches in one house without them accidentally controlling each other’s circuits. They are easy to program if you need to pair a single switch to multiple receivers or vice versa.VerdictIt’s a great price for the DEWENWILS switch that offers exceptional value. It is certified, providing peace of mind regarding electrical safety], and is backed by a 12-month warranty against quality issues.If you need the simplest, most reliable way to add a switch anywhere—especially for elderly users or hard-to-reach lights, or… if you’re sticking in a new light somewhere, but don’t want to make a mess, and dispense with all the extra wiring,…. Then this is the solution. Just make sure you check for that neutral wire and adhere to the 200W LED limit on the hardwired modules.Highly Recommended!

Fails after 18 months
Exactly as others have described. After 18 months the lights switch on briefly for a second then off. Changed the switch battery but still no good. It seems an “off” signal is either being constantly sent by the switch, or interpreted as received by the receiver. They were easy to install and worked fine up until this point. However I expect far more than 18 months use from such an item. Durability appears to be a problem.

Quick and easy no wire switching of circuits
Wireless receiver and two switch transmitters to control up to a 10A electrical circuit, this bought to enable a new LED strip light within an existing full glass conservatory room that would be difficult to place new switch wiring due to it’s open construction.The five foot LED batten wall mounted at the height of the conservatory eaves so wiring could be placed out of sight along the top of the wall, the receiver placed within a 35mm deep surface pattress box with blanking plate, this affixed on top of the fusebox so no wiring visible.Both switch transmitters placed adjacent to either entrance door originally using double sided tape but this changed to the two screw fitting provided as unable to support the weight of back box, small replaceable battery and face plate, the face plate just clips into place after fixing with just a slight movement top or bottom for on and off.Fitting complete the light worked without flaw, both switches about 30ft from the receiver and work perfectly, batteries are CR2032 type which are about half height AA batteries and readily available, quick, easy to fit and have already bought a second kit.

Wiring needed more explanation for after configs, but worked great once the receiver is installed
Wiring was very difficult as I’m not an electrical, my current switch didn’t have a live and neutral (it had L1 and 2 wires in COM), so I had to Google a lot and do all sorts of trial and error, but got it working in the end (took about 3hours to trying though). Then then one switch wasn’t working, and figured out that there was a battery faulty (was giving 0.61v instead of 12v) but I had a spare batter from an old doorbell that I used and worked fine. HOT TIP: i didn’t find it clear from the diagram, but the thin rocker (the part you press to use the switch) can be pulled off (with some force) so you can attach the screws properly.
