Drawing Pump Schematic

[balash]

The action of float switches is so confusing that even the experts get confused.

If you are filling a tank or maintaining a level in a tank, you want the High Level switch contact to be closed until the maximum level, then open at the maximum (open on rising level) to stop the pump.

Yes, Lancie's right. HL must be open above max level to shut off the pump.

I guess we have beat it to death, and it is past the time to quit.

True again. Everything that has to be said about this specific theme has been said...
