SJE MicroMaster® Plus WS

Mechanically-Activated, Wide-Angle Pump Switch

Pump switches provide automatic pump control.

The SJE MicroMaster® Plus WS pump switch is specifically designed as a mechanical alternative to the mercury-activated Junior Super Single® pump switch.  It directly controls pumps in water and sewage applications.

The SJE MicroMaster® Plus WS pump switch is not sensitive to rotation or turbulence, allowing it to be used in both calm and turbulent applications.
