Suraielec Wireless Light Switch and Receiver Kit, 15A High Power, No Wiring, 100ft RF Range, Programmable Remote Control 3 Way Wall Switches for Lamp, Ceiling Light, Fan, Outdoor Lighting

Good product
I bought two of these wireless switches because of the low cost to try and see how they worked. They were installed on separate breakers and light switches. They have worked well for about 6 months, and I am happy with the product. It does take a little electrical knowledge about wiring to install, but not complicated at all. The only drawback is you have to install the surface mount Decora style Pica transmitter switch within the wireless range of the receiver. Also, when there is a power interruption, you have to turn the switch off, then back on to reset it. The light does not come back on like a regular switched light will. This seems to be an inherit disadvantage to this technology and not the switch transmitter and receiver.

This one proved too difficult to install since the ceiling would need to be cut away
I decided to buy the other version that fits inside the ceiling electrical box. It does not require cutting the ceiling, but was a very tight fit. It’s in and working. Wiring is required, inside the box, contrary to the instructions. I had to disconnect the wiring to the original ceiling light switch, and remove the light switch, marking and insulating both ends of the wires, then wire in this new remote receiver between the power leads and the light. Be sure to position the receiver so that it’s LED and the push button face down and are accessible, since you will need access to them when adding a new wireless switch. The new wireless light switch installs easily on the old wall switch box because the backing plate of the wireless switch has holes that match the top and bottom screw holes in the switch box, so forming a new cover over the box opening. Adding the wireless switch to it is easy, since it just slides onto hooks on the box cover plate. This makes it easy to remove the wireless switch when the battery needs changing, or it can be carried around when you want it somewhere else temporarily, like carrying a TV remote, but it’s safer to add an additional wireless switch and leave this one in place where the original was.Making new or several wireless switches work with the receiver and light only requires the power to the light circuit to be on. Then you press and hold the black button on the wireless receiver until the Red LED on the receiver starts flashing. You can then release this black button, but it will time out if you don’t activate the wireless switch soon enough. If the LED stops flashing before you can press the wireless switch ON button you will need to press and hold the black button again to restart the pairing process again. With the LED flashing, press the ON button on the wireless remote. The LED on the receiver should stop flashing and the light should now turn ON and OFF with the wireless remote switch. If you want to add additional wireless switches to this receiver, repeat this pairing process for each wireless switch. I believe that you can add up to 8 of these wireless switches to this light.Charley

Easy to install. Very good range bought a second one

The electronics will eventually be damaged by the surge created when controlling the ballast located in the 120V fluorescents and LEDs.The remote was working at 435 feet, I couldn’t see the hangar behind two nabors house.I don’t know the maximum distance.I am in a country with no electrical interference except for coyotes and foxes.To reach over 135 meters, I believe the signal reflects off the metal box in the atic containing the 120 volt relay.

Works great
