Can you explain to me why you are using these relays on the lower switches?
Why not just parallel the lower switches with the upper switches and be
done with it? The problem with using an electrical switch with no or
little current through it, like this relay nonsense, is that the contacts
don't get cleaned with a good arc because the tiny current the relay uses
doesn't produce a cleaning arc. The 2-3A motor hardly fulfills this
requirement.

I don't like the rolling ball switches. Enclosed mercury switches, like
the Rule float switch uses, is self-healing and very reliable if you keep
large trash from holding it ON by getting under it. A simple screen
dropped over it fixes that problem. The Rule float switches in Lionheart
control the pumping overboard of all sink, shower, sump garbage that goes
down the drains. They work just fine! Maybe it's the dish detergent that
keeps 'em clean. It cleans the bilge of oil. "Dawn moves grease out of
your way"....even in bilges!
