I had a Rule (I think) traditional style flappy float switch, that failed after about a year in an always-on position, fortunately it was suitably fused so blew that before the wire caught fire although it did also manage to destroy the pump. Switched to an electronic switch (which IIRC was a Johnson something or other), that failed after 6 months in an always-off mode, I came to the boat with the bilge about 1/2" below floating the board off. Then I put in an Ultra Safety Systems, which 3 years down the line is still doing just fine. I imagine it will last a good long time, well designed, well built.

No more failures. Besides having a circuit breaker on the AC side of your charger, you should have fuses in the DC side, Alan Bergen 35 Mk III Thirsty Rose City YC Portland, OR
