Merrill Extra Heavy Duty Pressure Switch, 80-100

Merrill Extra Heavy Duty Pressure Switch, On @ 80psi - Off @ 100psi

The MPSXHD80100 Merrill Extra Heavy Duty Pressure Switch is an extra heavy-duty pump control switch designed for reliable water pressure management on higher horsepower pump systems. Factory preset to turn ON at 80 PSI and turn OFF at 100 PSI, it features an extra-large heavy-duty case for easier wiring, brass contacts for strong electrical conductivity, and heavy brass wire connections with set screws to securely hold No. 4 wire without slipping. Installation is simplified with a 1/4" swivel union so the switch case does not need to be pivoted, and a heavy fiberboard bracket provides strong, heat-resistant contact movement support.
