Short throw for confined space.
Original RULE switch (fairly new) would occasionally not "start" unless given some wave action, and needed a larger swing area under engine block. Heavy rain and calm marina was a recipe for disaster. After checking on boat and finding it didn't engage (starter almost under water on new 5L merc.) I installed this this one. 3 days of rain and every day I check it, it has done it's job more efficiently than RULE brand. Cheeper than a $25K engine replacement.

Durable Switch
Works like a champ. Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement.

Low Profile
It’s a flapper. Low profile. Works good.

So far so good
After a little over a year from installation, this switch still works well. I also purchased a SeaChoice model about the same time that has already failed. This has been the best level switch I've used in several years, including the "Rule" model. I have become frustrated with buying new switches every 6-12 months due to horrible quality. This one seems to be among the better ones but would still rather have a real old-time mercury-wetted, tried and true, type.

Solved the sticking problem.
The float switch would not turn off after pumping out the bilge. I put a package of five one ounce sinkers on top of the float held on by a plastic wire tie. It now turns off.
