Adjustable 40-60 PSI Range for Precise Pump Control - This heavy-duty water pump pressure switch activates your well pump when pressure drops below 40 PSI and stops it at 60 PSI, preventing low or high water pressure issues. Ideal for submersible, jet, and reciprocating pumps,its adjustable springs ensure accurate rising/falling threshold to match your system’s needs. Universal 1/4" NPT Design for Easy Installation - Featuring standard 1/4" female NPT threads, this well pressure switch installs in minutes and works with all electrically driven water pumps (submersible, jet, etc.). Perfect for 40/60 PSI systems, it’s a direct replacement for most residential and commercial well setups. Durable Silver-Plated Construction for Harsh Environments - Built with corrosion-resistant silver-plated contacts and stainless steel components, this water well pressure switch withstands extreme temperatures (-22°F to 257°F) and harsh conditions in pressure tanks or oil wells. The high-temperature-resistant housing ensures years of reliable service. Precision Diaphragm & Snap-Action Switch for Energy Savings - The precision pressure-sensing diaphragm and snap-action mechanism start/stop your pump only when needed, reducing wear and energy costs. Large contacts enhance durability, while automatic pressure regulation maintains consistent water flow for homes, RVs, or irrigation systems. Compatible with 40/60 PSI Systems & Trusted Support - Designed as a direct upgrade for 40-60 PSI well pump pressure switches (including Pumptrol models), this switch includes a 24-hour response pledge. Enjoy peace of mind with its extended lifespan and robust performance in residential or industrial applications.
