Works it's perfect, installed it easily and cycled.The pump a few times and the switch worked perfectly every time! This was the best value out there.And one of the very few places that had the switch that I actually wanted.

The Best Pressure Switches

The Merrill pressure switches do not get stuck like other manufacturers do. To me they are made of high quality materials.
