    Pressure Switches

    Pressure Switches with

    Manual On/Off Lever

    Activate or deactivate your electric water pump based on water pressure. These switches turn your pump off when pressure increases to the set pressure and on when pressure drops to the reset pressure. All are NEMA rated to stand up to some corrosion, but they shouldn’t be used outdoors. UL listed and CSA certified, switches meet American and Canadian safety standards.
    Low-Pressure Cutoff—Switches with low-pressure cutoff turn your pump off if water pressure dips 10 psi lower than the reset pressure. This stops the system from pumping when there’s an issue in your line, such as a leak or break, to avoid flooding or other damage. These switches will also resume pump control with their previous setpoints when turned back on.
    Pressure Switches with Manual On/Off Lever—Use switches with a manual on/off lever to turn off your system for maintenance or for long periods of time. When you turn them back on, they’ll resume pump control and remember their pressure setpoints.
    Pressure Switches with Pressure Surge Protection—Switches with pressure surge protection won’t activate during brief periods of high pressure. They’re often used in systems that have frequent pressure spikes.
