Review: Worked as advertised. Used to to add an exhaust fan heater to our bathroom. Rather than run a new line to a switch I just put this in series with the wire. I’m only triggering it from about 10 ft away, so can’t speak to the length of signal distance. Quality seemed decent, but there’s always a thought in the back of my mind that it might not really be 30A rated. I’ll let y’all know if my house burns down. Review: I am stunned. I was only about 40% confident this AC remote light switch would work. It is a game changer. I bought it to turn on a security light outside my woodshop. It works perfectly! Range from the house is around 100 feet through several walls. I mounted the receiver inside the shop in the peek of the roof about 14 feet high and it works first time every time. However the two remotes each have their own channel. It is very helpful that the remotes are interchangeable so they can be left in 2 different locations to turn the light on with one and off with the other ## Features - HIGH POWER LOAD:The Relay adopts 40A relay, which can load high-power electrical appliances.The relay is isolated by transformer, so it will not carry high voltage when outputting.

I bought it to turn on a security light outside my woodshop. It works perfectly! Range from the house is around 100 feet through several walls. I mounted the receiver inside the shop in the peek of the roof about 14 feet high and it works first time every time. However the two remotes each have their own channel.

We also have it on our water intake pump which is about 100' below our house and it works great. We are very happy with these and the 2 remote units don't share the same remote code so you don't accidentally turn on another pump with the other remote. They are easy to install and last a long time. ## Frequently Bought Together - dstfuy Wireless Remote Switch,AC 110V/120V/240V/40A Relay with Voltage Isolation,RF Remote Switch for High Power Water Pump,Dust Collector,Lighting Electrical Equipment with 984FT Long Range. - dstfuy Wireless Remote Switch 12V,1500M Meters Long Distance,DC 12V/24V/48V/72V /40A Relay RF Remote Control Switch for Water Pump Motor Lighting Farm Agriculture(Switch 12V) - 2000 Meters Long Distance Wireless Remote Control Switch high Power Water Pump Motor Lighting Industrial Wireless Remote Control Switch AC 110V 220V Relay Switch Transmitter High Range 6600ft --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/446166126-wireless-remote-switch-ac-110v-120v-240v-40a-relay-voltage](https://www.desertcart.vu/products/446166126-wireless-remote-switch-ac-110v-120v-240v-40a-relay-voltage) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
