Pressure Switch for Water Pumps
This Dayton pressure switch controls water pump operation with a factory-set 40/60 psi on/off range. It mounts via a single 1/4 inch FNPT port and uses a DPST electrical contact form rated for 1-1/2 hp at 120V and 2 hp at 240V. The unit carries CSA and UL certifications.
Adjustable Differential for Sustained Operation
The switch differential can be set between 15 and 50 psi within an overall 10 to 100 psi range. This adjustability lets the installer tune cut-in and cut-out points to match tank size and pump capacity, reducing short-cycling during prolonged demand. Standard action provides consistent response across the operating envelope.
NEMA 1 Enclosure and Wide Temperature Range
A NEMA 1 rating suits indoor installations where the switch is protected from falling dirt. The housing operates from -22 to 250 degrees Fahrenheit, accommodating cold basements and hot equipment rooms alike. No unloader valve is included, so plumbing must accommodate pressure relief separately.

Questions about this item
How much power does the 40/60 PSI pressure switch draw when the water pump runs all day?
The switch itself draws negligible power; it only carries the pump load rated at 1 1/2 hp at 120 V or 2 hp at 240 V single phase.
What pipe fitting must I already have to install this 1/4 in FNPT pressure switch?
You need a 1/4 inch male NPT thread on the pump or piping so the switch’s female port screws on directly.
Will this DPST switch work with my older single-phase motor that runs on 120 V?
Yes, it is rated for 1 1/2 hp at 120 V single phase and carries CSA and UL listings for that service.
