Boshart Industries pressure switch PS02-2040 is a pump pressure switch for well-water systems that helps maintain consistent water pressure by controlling when the well pump turns on and off in a 20/40 setup. In this setting, 20 psi is the cut-in pressure where the pump turns on after pressure drops, and 40 psi is the cut-out pressure where the pump turns off once the pressure tank reaches the set level, letting the switch start and stop the pump at set pressure points depending on system settings, all without requiring a control box.
It is a good replacement when the problem is unreliable pump control or pressure cycling.
This pressure switch is installed as part of a well system pump control setup using a 20/40 pressure setting. Review the manufacturer instructions and confirm the required pressure setting before installation.
Turn off power to the pump system before starting installation.
Remove the old pressure switch if replacing an existing unit.
Mount the PS02-2040 pressure switch securely in the system.
Connect the wiring according to the manufacturer instructions.
Restore power and test the system to confirm operation at the 20/40 setting.
