Meet the Merrill MPS3050 Water Well Pressure Switch, a dependable OEM replacement designed for electrically driven water pumps of all types. With a 30-50 PSI cut-in and cut-off, plus an adjustable differential, it helps maintain steady water pressure across your system without frequent replacements.

Built for durability, this switch features large contacts that open on rising pressure, a design choice that supports longer service life and smoother cycling as your system responds to demand. Rated at 2 HP on 115 VAC, it handles typical residential well applications with confidence. The 1/4" female NPT connection makes piping straightforward, and the NEMA 1 enclosure offers basic protection for indoor installations.

Key features

  • Cut-In Pressure: 30 PSI; Cut-Off Pressure: 50 PSI; Adjustable differential to fit your needs
  • 2 HP at 115 VAC, suitable for common well pump configurations
  • 1/4" female NPT connection for flexible plumbing options
  • Large contacts designed to extend life by handling cycling loads
  • NEMA 1 enclosure for indoor use and OEM replacement part packaging

Practical use and benefits

  • Residential well systems benefit from a consistent pressure range, reducing start-stop cycles and delivering steadier water pressure
  • Compatible with jets, submersible, and reciprocating pumps when used as an OEM replacement part
  • Individually boxed packaging simplifies inventory and swap-outs for service professionals

How it works: When demand rises, the switch is set to open at higher pressure, with an adjustable differential to tailor the response. The result is a dependable cycling pattern that can help your pump settle into a comfortable rhythm. This is a replacement part, not a full system guarantee, so it’s best suited for installations that match the listed specifications.
