Works fine
These are much nicer to install compared to the older switches -kind big for smaller boats-the removable base make rigging simple -have had better luck with these compared to the super switches rule sells-

Great option for backup sump pumps
I opted for another Rule bilge pump switch for my DIY backup sump pump system. This new switch will replace the one I had which was still working but had aged out. The switch is well put together, feels solid and is compatible with the side mount fitting (for Rule pumps) that came with the previous switch.

Easy hookup and install, game changer
My 1998 16’ Lund is a real leaker. After about 4 hours the water would start coming up to the floor. This required me to remember to turn on the bilge pump every so often. If I got preoccupied sometimes I’d forget creating extra weight in the boat. I was usually reminded when the bow trolling motor would surface and make a bunch of noise.Installing this switch has taken that out of the equation. It kicks on every half hour or so now. I bypassed the switch it was hooked to and tied it into the power going directly to my battery with a fused line. I know my Lund has a double hull but I really didn’t want to drill into it. I had a 1” thick piece of HDPE polyeurethane that I cut a block out of and screwed it to that, then glued it to the floor. Gorilla glue or a construction adhesive will work, I used a silicone based adhesive I had laying around. This also elevated it up just a bit from the pump so it will for sure shut off. If the float can’t drop down low enough it won’t shut off. If the float is at the same level as the highest point of the intake on your pump, this may happen.Now I don’t leave a trail of water to my house when I trailer my boat home from the river. The big advantage is I can leave it on a dock at a resort or cabin overnight or longer without worrying about finding it on the bottom in the morning. It also gets rid of rainwater as needed.

Nearly exact replacement for my 30 year-old OEM
Nice switch. My only grumble is that it does not have the “lock up” position that my OEM had, which was nice when wiping out the bilge. Otherwise, all good.
