Merrill Extra Heavy Duty Pressure Switch, 60-80

Merrill Extra Heavy Duty Pressure Switch, On @ 60psi - Off @ 80psi

The Merrill MPSXHD6080 Extra Heavy Duty Pressure Switch is a rugged, high-capacity pump control switch designed for reliable water pressure management, especially on higher horsepower pump systems. Housed in an extra-large heavy-duty case for easier wiring, it uses brass contacts for strong conductivity and heavy brass wire connections that securely clamp No. 4 wire with set screws to prevent slipping. Factory preset for convenience, it turns the pump on at 60 psi and off at 80 psi, and includes a 1/4" swivel union to simplify installation without needing to pivot the switch case.
