reaches 2" (51 mm) and will turn the pump off when

water level falls to 3/4" (19mm). They can also be used

to operate high water alarm systems.

This product must be fused with the correct

recommended fuse size for the pump to which it is

connected. Do NOT use these switches in applications

where the pump is operating above the maximum

current in the table above.
