A 10 amp DPDT 8 pin relay is very common. They come with wiring diagrams usually. **Q: Is this sutable for 12 gauge wire?** A: It’s been 3 months now since installation with no problems ! I Replaced a Merrill mechanical pressure switch which had the pump and power lines enclosed within it ! Along with one of the reviews that suggested plumbing reduction fittings, I had to add a Junction Box for the electrical wiring to house the 220 volt line and the line from the pump. I set the pressures for Low 55 # and Hi at 70 #. Will post in summer how it handles water pressure with the lawn irrigation. **Q: What is the correct wiring of the unit? Since no mention of the color coding is available. A diagram w/colors would be helpful.** A: Only color that matters is the green/yellow wire is ground. Other 2 are your 2 hot lines (110, 115, 120V) each leg. They are labeled on the back for power in, and switched power out. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by on Reviewed in the United States May 30, 2026* Easy to install and works fine. Much better than the mechanical switches I have used. ### ⭐⭐⭐⭐⭐ Works great - with suggested upgrade *by on Reviewed in the United States November 9, 2023* This switch replaces the disliked double spring controller used in millions of wells, and pressure regulators. It's absolutely great, easy to program, and can set the start (low) and stop (high) pressures to what you want.The single deficiency is that it switches one side of the 240 power, leaving the other side hot. We corrected this by adding a Potter & Brumfield Relay DPST, 30A Relay 220/240VAC with same voltage coil. The advantage is both power lines are on or off, and the controller load is the small current required to activate the relay, extending the life cycle of the controller. Power is managed by the relay, not the controller. ### ⭐⭐⭐⭐ Great In Theory—And It Wasn't The Problem I thought It Was *by on Reviewed in the United States June 24, 2026* I originally wrote a scathing one-star review, starting with, "I'm hoping to edit this review and add a few stars, because the concept is great: Emerge from the Dark Ages of mechanical (read: sticking) points and inaccurate pressure settings into the modern age of electronics and sensors (nothing can go wrong go wrong go wrong)."I mean, I installed this thing according to the laughably translated instructions, and voila! It worked—for maybe half a day. Then I got the dreaded E—F message which indicates that the pump is receiving no water from any or all of three cisterns. With a total capacity of 30,000 gallons of water, I somehow doubt that they all ran dry in half a day.So I was resigned to re-connecting the Square D switch from the Industrial Revolution that required a visit to the pump room to whack it when it reached the cut-off pressure—or buying a new one, which would have been total capitulation to the Luddites. But when I opened the junction box where the colorful matrix of wires and their little wire-nut hats reside, I saw that the mislead E–F message might just mean a broken circuit, for one of the load feeder wires had somehow freed itself from its wire-nut shackles; could it be that the problem was NOT the switch, by my own ineptitude at wire-nut installation? (Hey, I'm blaming the arthritis.)Spoiler alert. Yes—yes, it was. With the load feeds lengthened by about an inch (how do you make maires longer? It's a secret), I was able to re-twist the connections. Then I crossed my (arthritic) fingers and threw the 50-amp double breaker.And the pump began merrily whirring its way up from a pressure of zero toward the max I had originally set: 65 psi. As the system approached that number, of course, it took longer and longer to gain each pound... so I confirmed that it could reach a firm 64 psi, and then lowered the max to 63. I can live with that.I'd give it a fifth star except for the incredibly awful documentation on this thing. With a little added research, you can probably figure everything out, but I have better things to do than spend my life wandering the Interwebs looking for reliable instruction manuals. ## Frequently Bought Together - GamaTech Pressure Switch for Water Pump and Air Pump, Digital Adjustable Pressure Controller, 220V, 0-230 Psi,1/2" Male Npt - SDTC Tech 2-Pack Brass Pipe Fitting 1/4 NPT Thread Male to 1/2 NPT Thread Female Reducer Adapter - Legines Brass Reducing Coupling 1/2" NPT Female x 1/4" NPT Female, Hex Reducer Coupler Adapter Pipe Fitting 1200psi (Pack of 2) --- ## 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.za/products/505050347-gamatech-220v-230psi-pressure-switch-for-water-pump-and-air](https://www.desertcart.co.za/products/505050347-gamatech-220v-230psi-pressure-switch-for-water-pump-and-air) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-15*
