The Rule-A-Matic Plus Float Switch has a fully integrated, impact resistant cover which protects the internal float switch against debris and jamming. Same wire and switch features as the SuperSwitch.
Switch will turn the pump on when the water level reaches 2” (51mm) and will turn the pump off when the water level falls to 3/4” (19mm).
They can also be used to operate high water alarm systems.
This Model 37FA switch incorporates a waterproof in-line fuse holder so you don't have to add your own to the positive wire from the battery. A fuse prevents damage to both the pump and switch should an electrical problem occur.
