I was looking for an actuating voltage of 18-25 vac and this is not what that is. ### ⭐ Missing screws and plates on contacts. Useless !!!!! *by P***. on Reviewed in the United States 🇺🇸 on May 5, 2014* This item arrived today, we were in a hurry to get it installed as it is the last missing piece of a boiler system that we wanted to get started up while we still had enough cool weather to test the boiler.Unfortunately it arrived without the screws or the plates for the contacts. These screws are shown in the picture of the item, but are not included in the package. To make matters worse, the threads are not standard, I tried to take the screws off an old relay, but they didn't fit. Standard screws used with electrical components also did not fit.I decided it will be far easier to return this item, and order something else than, search for these specialized parts. Feels like a real bait and switch since they show a complete unit in the picture, but ship without essential parts. Unless you are in the business of stocking metric screws and contact plates, stay far away from this item. ### ⭐⭐ all 6 items came dead on arrival and I had to reorder *by L***N on Reviewed in the United States 🇺🇸 on March 30, 2019* couldn't get our sign to work with new relays. Electrician tested them and they were all dead. :( I hope this next batch works cause I can't get them anywhere locally. --- ## 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.ae/products/2165704-opto-22-120a25-ac-control-solid-state-relay-120-vac](https://www.desertcart.ae/products/2165704-opto-22-120a25-ac-control-solid-state-relay-120-vac) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-04-23*
