SEAFLO Heavy-Duty Float Switch - 12V, 24V, 32V, Mercury-Free, 25 Amp Capacity, Durable ABS Housing, 4-Year Warranty SFBS-25-03A

Replaced arm type, kept sticking in off. Used to make bilge pump automatic on boat. Also wired strobe alarm light on console, if bilge turns on I have audible and visual notifications. Very pleased with operation and installation instructions

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.

This was ordered and installed back in March (7 months ago) and it's worked well every time the boat was taken out since. The switch turns the bilge pump off and on automatically. No need to trigger it on your own. And it was very easy to install. Works great and so far has been very reliable.

Good Quality Built Float Switch for my Sailboat , can register it with SEAFLO to double warranty , I like that !

Very sturdy plastic construction with clear installation instructions. The float and the base come apart to make installation of the base on a weighted or stable surface much easier. This was one of the less expensive options I was able to find, but it has worked flawlessly and held up to a harsh outdoor environment with no problems. I don't use it as a bilge pump, I use it in my garden to stop the fountain pumps if the water runs low and it does that job perfectly.

I purchased these on January 6 within three weeks. Both switches failed, one would not turn off and the other would not turn on. These were the sea flow 02. So on February 11, I purchased 2 Seaflow 03s and both of those failed too. One worked for 6 months and stoped (no polarity). I installed the second switch and within a week the switch will not turn on and turn automatically. It won’t lift enough to turn on or return to turn off.

Incredable float switch right here. I used this float submerged in 175 degree water for over 3 weeks. It worked perfectly the entire time. Did not expect it to last due to the water temp. I was wrong. Pretty impressive float switch. Would buy again in a minute!!!

I forgot to pull the drain plug, turned off power and after a rain storm the bilge had 15" of water in it, the switch was standing up vertically and not working when power went back on. it float part seemed to slip around the switch shaft after a further inspection.....repair was done , but need for new replacement was more important than the $
