As shipped the antenna is a short curled up black wire. Leaving the wire curled up and testing the range I found I could get 150 feet from the receiver and the hand held remote transmitter was able to connect and control 100% of the time. As I went beyond that point out to 175 and beyond the receiver was having difficulty seeing the click of the remote. It would work intermittently only. Uncurling the wire and making it stand upright I repeated the experiment and was able to get out to 225 feet before the receiver was no longer able to reliably respond to the remote. At 225 feet it was 100% reliable. Beyond that I could get it to work intermittently. Great features with their system able to interchange remotes from one relay or the other. The ability to program each button is brilliant and very flexible. I'll use a two button remote to control my system and a three button remote to program my strobes and then put it away until needed later. The remotes feel good in the hand, not cheap. Installation is simple with two wires for + and - 12 VDC and then the relay one input and the two outputs. One output is normally closed - it connects to the relay's common input when at rest and goes off/opens when the relay activates. The second output is normally open - it is disconnected from the relay's common input when at rest and comes one when the relay activates. I attempted to measure the current draw of the receiver deactivated and the current draw is so small my digital meter does read it - it's less than 0.01 amps. With the relay activated I read 0.025 amps or about 1/3 of a watt power so this thing is very frugal. I have no concerns about leaving this on my car battery for weeks and months at that low of a drain. There are no written instructions included so just print out the photo here or follow the video. I bought a total of five of these relays and will likely buy more. Good product. Review: Easy to use if you know HOW! - Excellent. So just remember these things if you are wiring this (I used it as a momentary switch): 1) you need a separate POS and NEG cables to power this remote relay device as it needs power for receiving signal and operating its relay (yes, you can run it off a 9v battery if you'd like). They get wired into the V+ and V- ports. 2) you plug a LIVE positive wire directly into the device that requires powering (actuator, DC device, horn, light, etc).and NOT into this wireless relay - You plug the LIVE negative wire into this wireless relay and the NEG wire for the device also into this relay. So this wireless relay ONLY operates on the NEGATIVE wiring. The photo attached indicates exactly what's required. Study the photo well. 3) You need to program the remotes. Easy enough. Just press the button on the circut board and while the red light on the board is on, press the remote. Do the same for the other remote. Signal strength is strong - I didn't need to fully extend the coiled antenna cable and it operates from around 8 feet away. Perfect for my needs (popping the hatch of my van). Stuck the other remote onto the hatch as an easy way to open it from the inside. Immediate button press action. No delay whatsoever. ## Features - The volume is small and the performance is stable and reliable, high receive sensitivity, Signal can pass through walls, floors and doors.

Can I set up 6 relays and transmitters so there is no cross talk?** A: Yes, as long as you pair the relay and transmitter separately **Q: Does this only work with a dc power supply? one picture in the product description showed "110/240v live line" but this doesn't seem realistic.** A: This device is powered off 12v DC, and comprises a radio receiver and mechanical relay. It has an uncommitted set of relay contacts that can however switch any voltage, from a few volts (AC or DC) to 110v or even 240v AC. I would be careful at the higher voltages as the screw wire connectors are small and closely spaced. The relay is a compact packaged part that is energized by the on board radio receiver recognizing the unique code of the transmitter fob when it is pressed. So if you want to switch on a 60W lightbulb you would provide 12v to the receiver circuit and use the built-in relay to control the ‘live’ wire from a 115v wall socket that the lightbulb would plug into, much like a regular light switch. **Q: Can I connect several switches to work with the same remote?** A: The switch will only work when the 433Mhz transmitter is pressed, so as long as the remote is transmitting the correct frequency it will operate, **Q: Will this work for an old chamberlain/ sears opener? Guess it’s more of an opener question - I don’t know if those old openers use momentary switches** A: You could definitely wire something into the existing button by splicing in wires that short the leads to the botton when the relay is activated, or doing the same up on the opener if it has the typical exposed terminals. Another thing to consider is that you are going to need a 12V power supply to power this board. Those can be found for under $10 on amazon as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fairly decent range *by P***. on May 1, 2020* One of my concerns was adequate range of the remote control so I preformed some measurements before I installed these in my Jeep to control the rock lights.

These RF relays are great. I can operate lights using the provided FOB from inside my truck or outside the truck even when driving down the road. Run your pos/Neg up into the engine bay and wire to the relay. Program the relay and your done, no drilling or fishing wire through the firewall. Currently I have 2 relays installed one for LED's around the GMC logo on the Grille and one for a set of 7 inch LED driving lights.. I mounted a bus bar for positive and negative and connected the bus bars to my battery so I could have multiple 12V power sources off the Bus bar and multiple ground connections off the Negative bus Bar. I programmed the relays to open and stay open with 1 click and then turn off when clicked again. Comes with instructions pretty self explanatory if your familiar with 12V wiring. Run you hot wire to V+ and ground to V- . You also have to run a hot wire from your battery to the COM port. So your input to the relay will be 2 hot wires and 1 grouhd from your battery. Your output will use the NO port to lights etc...Make sure when coming out of the NO port you put an inline fuse to protect your device the relay is operating. Follow the included instructions to setup the relay the way you want to use it. Once you have power to the relay click the button on the Relay 8 times to clear any programming, the light on the PCB board will flash quickly then go off. for my installation constantly on or off I pressed the programming key twice, The LED on the relay circuit board will light up steady, press the key on the Fob you want to control the relay. your device should come on, press it again and the relay will open and your device will go off. So far pretty impressed for the price point. ## Frequently Bought Together - QIACHIP DC 12V 1CH 433Mhz RF Wireless Relay Remote Control Light Momentary Switch Transmitter with Receiver (1 Relay) - SmoTecQ 12V 2A Power Supply AC Adapter 2 Pack for CCTV Security Camera, Led Strip Lights, Router, Printer, Breast Bump and Other 12 Volt Electronics Devices Less Than 2 Amp - DieseRC DC 12V 24V 30V Secure Remote Control Switch Universal Wireless 433Mhz rf 10A Relay Receiver Board with 2 Transmitter Key fobs for Motor Light Gate Door DIY Wireless Controller --- ## 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.co/products/150280585-qiachip-dc-12v-1ch-433mhz-rf-wireless-relay-remote-control](https://www.desertcart.co/products/150280585-qiachip-dc-12v-1ch-433mhz-rf-wireless-relay-remote-control) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-15*
