02 Series Bilge Pump Float Switch - 12V/24V 18A Automatic Water Level Switch with 1m 16 AWG Leads, Sensor for Marine Boat Fresh & Salt Water Bilge Pumps, 4-Year Warranty

parfait remplacement pour ma pompe de puisard à batterie. Beaucoup plus précis et plus facile à positionner dans un endroit restreint que mon ancienne flotte à gravité (tethered float). Mécanisme plus fiable.

Don't buy the reed switches, they don't last. In addition, the reed switches fail with the circuit CLOSED. That burnt out 3 of my bilge pumps before I realized why the pumps failed. I run my bilge pump/float switch directly connected to a 100 watt solar panel (no battery). When the cheap reed switches fail they run the pump continuously until it overheats and dies—because all the water has been evacuated long ago. Since I bought one of these more expensive steel roller ball switches I've had no bilge pump failures every month or two. My pumps run all day off and on and those cheap reed switches can't take it.

Garbage sticks on and some more times doesn't come on at all..

It goes up and down, turns on and shuts off my bilge pump. Taking a guy out to hunt a shark. Might need a bigger boat.

New out of the package, the marine repair shop installed this switch and found it left my pump in a ‘constant on’ state whether the float arm is up or down. The seller sent a replacement switch but a simple continuity test with a multimeter (look it up, seller!) showed it too had the same flaw. Both units were sent back to the seller with a plea for better testing at the factory.
