I know what you mean about the Rule switches. I use them but have lots of spares on hand. However:...
I have a Johnson brand bilge pump and switch in my dinghy that works very well. It is a small pump, like you would expect for a dinghy, and includes a small (about twice the size of a cigarette package) switch that attaches to the pump. It is a sealed plastic box with two wires coming out of it. Apparently it uses capacitance sensing. You can test it by holding two fingers on two spots on the case. It gets mostly rain water but has worked well since I installed it a couple of years ago. Many years ago I saw a float switch on a friend's boat that used a plastic toilet float, piece of 1/4" threaded rod and a normal household toggle switch in a plastic handy-box. He said it worked well. So I made one on my boat with a ss spring to pull the switch up (ON) and a string tied to a gallon milk jug partially filled with sand as a float in the bilge. It has worked flawlessly for three decades. The switch handle has a hole drilled in it with a wire gizmo to attach the spring and the string. So some float switches do work fine and last a long time, just not the kind Rule makes.
