There is the A/B remote, the single button remote, the A/B/C remote, and the brushed-metal A/B/(C/D?) remote. I thought I was getting A/B but I got the single button. Just review your selection more carefully than I did. Very easy to set up and wire. The instructions are quite good considering other similar products that may not come with instructions at all. I like that there's both an NO and an NC relay built into it for versatility. Review: Simple, Basic and Just Works - Works great. The English User's Guide is attached. ## 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 β€˜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 ### ⭐⭐⭐⭐⭐ Great little RC switch *by A***E on January 6, 2026* Works exactly as advertised but be warned that there are several different remote control options and I did not get the one I was expecting (my fault, not theirs).

The English User's Guide is attached. ### ⭐⭐⭐⭐⭐ Easy to use right out of the box *by M***N on October 18, 2025* I used this to make Halloween prop / animatronic remotes. It was so easy to wire a 12v power source, connect the wires, and power it up. The remote paired instantly and putting it in momentary mode was simple. This worked so well out of the box. Excellent value. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/150280585-dc-12v-1ch-433mhz-rf-wireless-relay-remote-control-light](https://www.desertcart.kg/products/150280585-dc-12v-1ch-433mhz-rf-wireless-relay-remote-control-light) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-05*
