40-60Psi NPT Water Pump Switch

A mechanically operated pressure switch built from sturdy grey plastic, designed for integration into electric water pump circuits requiring automatic on/off control. It connects via a 1/4 inch female NPT thread and offers fully adjustable cut-in and cut-out settings between 40 and 60 PSI. As system pressure increases, internal components open the electrical contact—stopping the pump safely and consistently. Its compatibility covers all major electric pump types used in UK domestic water boosting: jet, submersible, and reciprocating models—making it a versatile solution for pressure tank-based systems.
