Suraielec 3 Way Wireless Light Switch, No Wiring, No WiFi, 100ft RF Range, Pre-Programmed, Expandable Wireless Wall Switch and Receiver Kit, Remote Control Light Fixture for Lamp, Ceiling Light, Fan

If you are at all comfortable with electricity, the wiring of the 'receiver' in an electrical box or ceiling fan is straight forward and adequately explained. First, of course, turn off circuit at breaker, verify, and then make your connections. The reciever is a small box with 4 wires, two neutral (tpyically white in most house wiring) and one lead for power source (120v) and one lead for the 'load' or device to be controlled. The wire colors on the receiver do not match these colors, so you need to read the label on the box to confirm your proper connections. If your switch box is really crowded with wires, putting the receiver in the box may be a bit of a struggle, but we did several and always managed to get it to fit. Simple case: one way switch for ceiling light: receiver is installed in electric box behind the original light switch, the original switch is replaced with the new 'transmitter' switch which is mounted on the existing wall box, job done!. If you have a second transmitter switch you can put is anywhere (wall mounting hardware included). Note this will not work easily on a multigang box since the switch is a self contained Decora style swith and built in cover. (You can mount any of the controlling 'transmitters' pretty much anywhere and coule even leave the original switch ain the box and add the transmitter after the switch, as a kind of master control. The system is very flexible and if you are reasonably electrically minded, you can even replace three way normal switches with four way and more. The transmitter can be installed, for example, in a ceiling fan canapy, to control the light separately from the fan, Again, you need to be reasonably comfortable with how ceiling fans are wired, power at ceiling fixture, v, power at wall switch, two wire v three wire, etc. Also note, you can not integrate dimming or motor speed in the basic system unless the dimming and/or motor speed controls come after your new 'receiver'. Extra switches and outlet controllers can be added, and programmed to work with the same transmitter. Each purchased set is pre programmed to for the transmitter switches to work with the supplied receiver. If you buy two sets, for example, to use in diferent rooms, no problem of conflict. But you can also reprogram them all to work with the same switches. We had a little trouble with the cryptic instructions re programming, but got quick help from the vendor. Also, we did not test the distance claim since all our uses were within a single room. We had some issue with line of sight but behind furniture failure to always work, but minor adjustments in location of switch, or receiver seemed to solve the problem.Switches use 12 v batteries which retail for about $1, we do not know how long they will last, but the battery is only used when the switch is pressed on or off, so it should be a long time. We like this inexpensive way to improve lighting control convenience at a good price.

One of the 2 switches was a little smudged and dirty, but that's ok, since this was a USED pre-bought item at a discounted price. Quality seems just fine. Install was fairly easy for someone handy, and works fine so far, only two days in.

Im only giving this 4 stars because, as others have pointed out, sometimes the switch doesn’t seem to work.Note something though, this is not an ordinary on/off switch that you can feel when the switch flips up or down. This is more of a push button switch, so that design may have to do with the “delayed” response. For me, it works 95% of the times and I’m happy with that.

UPDATE May 5, 2023: these remotes have continued to work great and have fully met my expectations. Haven’t had to change the battery on any of them yet.—-June 2, 2021: Pretty happy with it so far. Installed a couple of these sets over the last 2 days. One was installed in an exterior soffit outlet that controls fairy lights. Another was installed to control a door motion sensor light on an exterior garage.They did wire in easily (I had help from a family member knowledgeable with electrical wiring), and the controller fit well into standard old work boxes. Controller works fine even though my older home (1940's) has most circuits with no neutral wire. Remote switch range was tested at probably 25 feet from inside of my house, and worked reliably with no problems. You can hear a quiet "click" when the little relay in the controller switches on or off. The switches themselves are as quiet (or quieter)Pros:1. Affordable: 2 remotes + controller2. Quite easy to install, even in a house that has less-than-optimal electrical wiring3. Remotes already paired to controller4. Additional remotes can be paired to the controller if necessaryCons:1. The remote switch plate can't really be mounted in a standard outdoor waterproof box. I thought I might be able to grind the outside to make it fit, but it's too large, and the battery would get in the way...would take waaaay too much customization. Would be really great if they made a lower-profile version that would actually fit inside a Decora switch space.2. The switch itself works a little different standard Decora rocker switch. Clicking the top part of the rocker turns "ON", clicking bottom part of rocker turns "OFF". You also don't get the tactile feel of the switch being on or off; you have to check whether the light is on or off.3. IIRC this was not compatible for one of my applications (a 2-wire dimmer circuit in my dining room); this is minor, because I didn't expect this one to work with a 2-wire dimmer circuit. Had to buy a different and significantly more expensive product (4x the price!)I give the product 5 stars for now, and will revise in 12 months or so, based on the reliability and performance of the device. Will be interesting to see how long the switch battery lasts.

One of the switches across the room works great, the other it right next to the device and just doesn’t work

I had a pull down closet light with no light switch. This was a prefect switch and easy to install. I do recommend flat surface light fixtures is the option because anything else might over fill the light box.

There are two switch modules. One is bad and drains the battery in minutes. The other switch module and main receiver function fine. Cost $17.00, really not worth my time to return it as I live in the country.Update 03/14/25 discovered that the receiver and one working switch module only function if within 20 feet of each other. Even with receiver is outside of wall box. Don’t purchase.

The product was easy to install, however, having installed several of these wireless switches by this brand, I HIGHLY recommend going with the upgraded version for the extra $10 because even only 5' away, this switch has a hard time working properly. Either the transmitter is not receiving the signal, or the vice versa. Will be returning this and going back to the upgraded version.
