Mechanically-Activated, Wide-Angle Pump Switch
The SJE PumpMaster® SPDT pump switch is designed to directly control pumps up to 1/2 HP at 120 VAC and 1 HP at 230 VAC in potable water, water and sewage applications.
The SJE PumpMaster® pump switch is not sensitive to rotation or turbulence, allowing it to be used in both calm and turbulent applications. It can be wired to work in either pump down (normally open) or pump up (normally close) applications.
