Review: Durable Switch - Works like a champ. Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement.

Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement. ### ⭐⭐⭐⭐⭐ Great Deal *by J***Y on February 9, 2025* Good Quality Built Float Switch for my Sailboat , can register it with SEAFLO to double warranty , I like that ! ### ⭐⭐⭐⭐ Easy to install and working reliability *by A***R on October 8, 2016* This was ordered and installed back in March (7 months ago) and it's worked well every time the boat was taken out since. The switch turns the bilge pump off and on automatically. No need to trigger it on your own. And it was very easy to install. Works great and so far has been very reliable. --- ## 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.co.uk/products/145519938-03-series-heavy-duty-bilge-pump-float-switch-for-12v](https://www.desertcart.co.uk/products/145519938-03-series-heavy-duty-bilge-pump-float-switch-for-12v) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-05*
