OK, I have a Rule-Mate 750 (the biggest pump I could get that would connect
to my existing 3/4" hose), It has an enclosed float switch; I think it has
three wires: black, brown, brown/white. I have a West Marine Three-Way Panel
Switch with fuse. I think I may have to remove the pump housing from the
base, which is screwed to the deck, to manually check the operation of the
float.
I'll probably go to West Marine tomorrow and check one out on the shelf.
Almost everybody is showing a link except you Bill. Any how here is my
2CW.

You are correct. Split it from its base, and tickle the hidden
(protected) mercury float switch.
Can't you use a garden hose instead of driving around town?
