I feel a switch is important - it needs only be a simple on/off switch in
parallel with the float switch.

I believe that is what I said. At any rate I agree and that is exactly
how I have mine wired. It is the three way switch that allows you to turn
the pump completely off so even the auto doesn't work that I object to.

If people are so dumb as to leave it switched off then perhaps they
shouldn't have a boat anyway.
