Had the same problem as Joe. After less than a years' use the float mechanism turns on the pump but when water level receeds the switch sticks on so pumps stays on.

I replaced my old bilge pump float switch with this one last summer. It just failed in a permanently on mode over the last month and toasted a brand new battery.

I was looking for a direct replacment,what i received is not the same as the picture shows. I received a Rule Model 40A. This functions the same but is very different in size, I am using this new one in hope it is better than the one in the picture. The pump switches are not very durable, the warranty is 2 years and they fail right around 2 years. Mine have not failed within the warranty period. If your boat has a boss to mount this the new one is larger than the one in the picture and requires significant work to install

Same problem as others. The float constantly sticks in the "on" position, so I have to reach down into the bilge and slap it to get it to shut off. This is a major safety issue if you're offshore trolling and it runs the bilge when you can't hear it. It can easily burn out your pump or even worse drain a battery.

I had read a few negitive reviews of this product so I tested it thourghly prior to installation. The main concern was that it might have had negitive reviews due to the float switch hanging up on the housing. I inspected the action of the float switch and could not find anything that would cause it to hang either in the open or closed position. For this installation I needed a protected housing around the float switch since it was in an area where other objects could possibly fail and block the float. I repeatedly turned the switch upside down to activate the switch and submerged the switch in water. Everything worked as expected. I rated this a 4 since it worked under my test. Siince it is connedted to a secondary bilge pump I will not know how well it works in real conditions unless the water gets pretty high in the boat...I never wnat to hear this pump go off!
