Solid state float switch is significant improvement from what it is replacing
I installed the search over the weekend and worked during testing. The solid state design does away with all the problems of a regular float switch (debris is not going to freeze the float in the down or up positions)

Junk...
Junk... I bought 2 and both of them malfunctioned within days. The pump remained on, even when there was no longer any water remaining. This sensor should have cut the power to the pump and it did not. I bought another brand and time will tell if that works.

Failed after one month
It will never turn off. It runs until your battery is dead or pump burns up. Do not buy!!! The company will not respond to three email.

Great Bilge Switch
This bilge switch is great.The best thing about this bilge switch is that it has zero moving parts. That means no break downs!Once the water reaches the top hole, it activates the pump. It couldn't be any easier.

Works Flawlessly..Update, won’t turn off Update…now works flawlessly
Second Update….after carefully wiping the contacts the unit now works flawlessly.It could be that there was some oil, grease, or silicone on the two sensor pads.Update after using for a month…the unit comes on just fine but won’t turn off unless I wipe the contacts with a tissue. I’m on a cruise so won’t be able to return this for several months. The failure to turn off seems to be a common issue, even if relatively rare.This replaced a 12 year old unit which has just failed. Easy to install and test. Works flawlessly
