Same as the Bluesea Systems ones that everyone talks about. ### ⭐⭐⭐⭐⭐ Nilight makes more than great lights *by A***. on March 11, 2026* I absolutely love Nilight products. Works great will carry my 3500lb winch on my sxs easily. Was having a power drain I could not find I tried a cheap one local and it burned up this one handles the amp draw just fine ### ⭐ Don't believe reviews saying this is durable. Read this. *by J***Y on October 17, 2025* I want to start out by saying I normally like Nilight products, but this type of switch must be the worst design on the market across all switches. The only thing that holds the entire knob on is a tiny little piece of thin round plastic that's about 1/4" in diameter. There is nothing durable about it. I bumped into it while I was squeezing past the area that I had it mounted and the knob snapped right off... just by me bumped into it with my leg. You need pliers to rotate it once it breaks off. If anyone that has this switch and doesn't believe me, you can see how the little black cover is clipped in to the knob in my picture and you can easily remove it and check your own to see how ridiculously brittle that whole connection is. --- ## 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.sk/products/613710911-nilight-battery-disconnect-switch-200a-master-disconnect-isolator-12v-48v](https://www.desertcart.sk/products/613710911-nilight-battery-disconnect-switch-200a-master-disconnect-isolator-12v-48v) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-19*
