this dual float switch did the job well

bought a dual float switch to replace a single-level switch that was not giving enough control. the size was suitable for my tank setup, and mounting it was not complicated. I checked the on/off points a few times before putting it into regular use. it is a simple device, but it has been reliable for keeping the water level under control.
