Dayton 40/60 psi Pressure Switch

The Dayton pressure switch controls water-pump operation with a factory-set 40/60 psi on/off range. It uses a DPST contact form and carries CSA and UL listings for use in standard residential and light-commercial water systems.

Check Your System Before Ordering

Verify the pump voltage matches the 120 V or 240 V single-phase ratings and that the motor does not exceed 1-1/2 hp at 120 V or 2 hp at 240 V. Confirm the piping accepts a 1/4 in FNPT port and that the operating temperature stays within -22 to 250 degrees F.

Ideal for Standard Well Pumps.

This switch suits installers replacing a standard 40/60 psi control on a compatible single-phase pump. Buyers who need an integrated unloader valve or a differential outside the 15 to 50 psi adjustable range should look at other models.

Questions about this item

Does the switch come with any fittings or wiring, or must I supply the 1/4 in FNPT connector and electrical cable myself?

The unit includes only the pressure switch with a single 1/4 in FNPT port and DPST contacts; pipe fittings, tubing and electrical wiring are not included and must be purchased separately.

Should I select a different pressure range or a model with an unloader valve for my water-pump system?

This model is fixed at a 40/60 psi on/off setting with a 15 to 50 psi adjustable differential and no unloader valve; choose it only if those exact settings match your pump requirements.

Will the 1 1/2 hp at 120 V or 2 hp at 240 V rating handle my motor’s starting current without contact welding?

The DPST contacts are rated for 1 1/2 hp at 120 V single-phase and 2 hp at 240 V single-phase, matching typical residential water-pump motors within those limits.
