Review: Works as Advertised - 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: Works Very Well - We have this on our well pump and it's great. 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. ## Features - HIGH POWER LOAD:The Relay adopts 40A relay, which can load high-power electrical appliances to ensure long-term stability control.(Note:max load:30A) - STRONG SIGNAL:Adopts RF technology ,this remote lighting switch can pass through walls, floors and doors, control receiver from any place within a reliable distance.Max range is up to 984ft with no obstacle. - EASY TO CONTROL:Learning code has high-level security for its low repetitive rate and re-learn mode, it can delete the old code and re-learn a new code.There is a switch key on the relay.If the remote control get lost.You also can always control of it. - HIGH SENSITIVITY- Sensitivity -114dBm,Stable and reliable performance,high receive sensitivity and anti-jamming capability. - WIDE APPLICATION:This remote relay switch used in lamps,electric doors,water pumps, motors, windows,gate,industrial control and security industry and other fields. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08XQCLN4M | | Battery Types | A23 | | Brand | dstfuy | | Brand Name | dstfuy | | Button Quantity | 2 | | Colour | Remote Switch--110V-240V--984FT | | Connectivity Technology | Radio Frequency | | Controller Type | Button Control | | Customer Reviews | 4.4 out of 5 stars 77 Reviews | | Manufacturer | dstfuy | | Manufacturer Part Number | TO-03 | | Max Number of Supported Devices | 1 | | Maximum Number of Supported Devices | 1 | | Maximum Range | 984 Feet | | Model Number | TO-03 | | Network Connectivity Technology | Radio Frequency | | Number of Batteries | 1 Lithium Ion batteries required.

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 ## 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.gr/products/774360049-wireless-remote-switch-ac-110v-120v-240v-40a-relay-voltage](https://www.desertcart.gr/products/774360049-wireless-remote-switch-ac-110v-120v-240v-40a-relay-voltage) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-31*
