Seem well built & reliable so far ### ⭐⭐⭐⭐⭐ make sure the high/low signal switching jumper needs is set right *by E***E on 28 May 2024* *Be aware that the relay component on the items doesn't match the spec of the one's on the listing though (blue vs black, for one), but the differences are marginal - just be aware is my advice.**The main thing I'd mention first is that this particular relay has is configurable between high/low trigger, I had to swap the jumper for my first project to 'high' as it was default to a signal low trigger - I assumed the board was working fine because the (helpful) indicator led's were all fired up - so as soon I figured I needed to swap it to signal low trigger it worked swimmingly. I'm using it in my 3d printer to use the onboard 0.3a current-limited JST header (that normally powers the rubbish stock LEDs) as a 5v signal to trigger a higher capacity 5v feed for additional lighting - so I can control it using the stock on/off options. It was quick to get it all working as planned with this relay, and the output seems to work fine with DC instead of AC too. ### ⭐⭐⭐⭐ Decent, but a bit scuffed so i dropped a star. *by T***S on 9 September 2025* This little 5V relay has been great for a few Arduino projects. It worked right away, and there have been no issues with relays sticking. The build quality feels perfectly solid, although they were obivously hand soldered, and a little scuffed, but they all worked fine, so couldnt fault them, It wasn't used for anything with a massive load, but it was a nice solid click no weak coils. --- ## 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.de/products/654061798-innfeeltech-3pcs-dc-12v-relay-module-1-channel-relay-optocoupler](https://www.desertcart.de/products/654061798-innfeeltech-3pcs-dc-12v-relay-module-1-channel-relay-optocoupler) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-23*
