Diagrams don't work!** A: These modules work OK as I have used them many times. The relay connections are labelled 'ON' and 'COM' on the PCB. You need to connect the 'COM' to your 6 V supply voltage. The device you are trying to power connects to the 'ON' connection and then back to 0V (ground). The relay cannot handle much current 1 A max but typically <700 mA. If you need more current you can use this to drive a power relay where the coil of the relay becomes the device you are switching. The power relay then drives your device. **Q: By the description, does this mean the remote can be powered using 5V Too?** A: The remote uses a PP3 9v battery (included). Don't yet know how often they need changing as I'm still on the original one. I doubt it would run on 5v, but can't see why you would want it to. **Q: Can the remote transmitter be powered by 12v instead of 9v?** A: The differential voltage should have minimal effect but if you are cautious then add a voltage reduction circuit to the 12v supply **Q: What is the curly lead for in the photo. It is not in the wiring diagram** A: That’s the ariel. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfecto *by C***N on Reviewed in Spain on 30 May 2020* Perfecto ### ⭐⭐⭐⭐⭐ Funktioniert super! *by N***S on Reviewed in Germany on 25 April 2020* Also ich habe diesen Schalter in eine Computermaus eingelötet welche baugleich wie die einer Arbeitskollegin war und ausgetauscht. Die 5 V USB Spannung waren ausreichend für die Stromversorgung und ich konnte per Tastendruck bequem die Funktion der rechten Maustaste an und ausschalten.Hat sehr gut funktioniert und war der lustigste Arbeitstag den ich je hatte. ### ⭐⭐⭐ Stromdaten / zu hoher Verbrauch *by W***N on Reviewed in Germany on 18 August 2020* Das Produkt tut im Prinzip was es soll, jedoch für mich wegen der zu Hohen Stromaufname in einem mobilen Gerät (Fahrradalarmanlage) unbrauchbar.Ich bestrome die Platine mit einer 9 Volt Batterie, gemessen 9,3 VAufnahmestrom im Ungeschalteten Modus (nur Empfang) liegt bereits bei 7,3 mA, also 68 mW Verbrauch. Damit komme ich auf etwas unter 50 Stunden Laufzeit mit einer 9 Volt Block Batterie (3,3 Wh). Ohne Schalten.Im Eingeschalteten Zustand steigt der Strom auf ca. 68 mA an und bleibt dort dauerhaft (KEIN Bistabiles / Toggle Relais!), der Verbrauch steigt somit auf 630 mW. In 5 Stunden wäre meine Batterie leer.Das Relais schaltet lt. Datenblatt ab 3 Volt, wird aber mit 4 Volt bespannt und hat einen Innenwiederstand von 65 Ohm. Hier erklären sich die zusätzlichen 61 mA.Leider sind die gemachten Angaben zum Produkt sehr optimistisch, vor allem hatte ich ein bistabiles Relais erwartet, was aus der Beschreibung nicht hervorging. --- ## 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.pl/products/79196532-dc-3-7v-12v-1-channel-secure-rf-relay-wireless](https://www.desertcart.pl/products/79196532-dc-3-7v-12v-1-channel-secure-rf-relay-wireless) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-21*
