Would return item, but it is not worth the time or effort. I had to modify them in order to attach wires securely to the terminals. ### ⭐⭐⭐⭐ fine switch *by H***I on August 17, 2013* This was a fine product, the only problem was that the picture is very deceiving. You think you are getting 4 switches, when in reality it is only for one switch. Whichever switch they are selling should be the only one in the picture so that you know exactly what you are getting. The picture should match the description. I was disappointed when one switch showed up instead of four. --- ## 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.uy/products/18410207-knife-switch-double-pole-double-throw](https://www.desertcart.uy/products/18410207-knife-switch-double-pole-double-throw) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-05-22*
