Note: 3-wire flow switches work with older 4-wire cells, but 4-wire switches cannot be used with post-September 2018 new cells. When installing a 3-wire flow switch on an older 4-wire cell: Green wire (from the 4-wire cell): Connect directly to the cell—do NOT connect to any wire on the 3-wire switch; White wire: Match the 4-wire cell’s white wire to the 3-wire switch’s white wire; Red wire: Match the 4-wire cell’s red wire to the 3-wire switch’s red wire; Black wire: Match the 4-wire cell’s black wire to the 3-wire switch’s black wire. ## Features - 【NOTE】IntelliChlor cells manufactured before September 2018 use 4 wires (red/black & green/white) for switch connections.

Thank goodness this part fit and works. I see durability is an issue for some. If it craps out I’ll be back but for now it’s the best 19$ I’ve spent in a long time. ### ⭐ Poor Quality *by A***Z on July 6, 2024* The metal tab on the switch broke after 30 days. There is a reason this is 1/5 the cost of the OEM flow switch. Materials are cheaper. Recommend spending the money and buying the OEM. ### ⭐⭐⭐⭐⭐ Came on time.So far it work great! *by F***K on March 16, 2024* Existing chlorine generator has a green forth wire (I think it is for a ground) On the new Flow Switch there are only three wires, no fourth green wire. I terminated it by taped it off . Did I do the right thing?Thanks!FTink ## Frequently Bought Together - DELEYAPARS New 520736 Flow Switch with 3 Wires (Black/White/red) for Pentair IntelliChlor Compatible with IC15, IC20, IC40, IC60 Cells Manufactured After 2018 - AR-PRO 520670 The Exact Acid Washing Kit Replacement | Compatible with All Pentair Intellichlor Salt Chlorinator Models| Made of Premium, Heavy Duty Plastic - Improving the Parts Lifespan by 50% --- ## 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.th/products/604108162-520736-flow-switch-with-3-wires-replacement-for-pentair-intellichlor](https://www.desertcart.co.th/products/604108162-520736-flow-switch-with-3-wires-replacement-for-pentair-intellichlor) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
