So far more reliable than micro switch
I am happy with this purchase. So far, the contactless switch has been more reliable than big brand bilge switches that depend on a micro switch lever for turning on and off my bilge pump. My problem with micro switched float levers is they don’t always turn off after the water levels drop. The Whale senses when water is present at the level of where you place the Whale. It works, no moving pieces to worry about. You still need to keep the bilge clean but no longer have to worry about a switch stuck in the on position, draining my battery.

The best bilge pump sensor yet!
For years I used the Water-Witch sensor on my main bilge pump - still works perfectly. But when installed now a secondary/backup pump, found this little one to be the absolutely best out there. It has a better reliable technology, more compact and with more options to mount. Only two wires, so way more straightforward and simple to install and control. Also priced better. Highly recommended!

Switch fails...it turns on to activate the pump but does not turn off
The switch turns on when we get water in the boat from rain, but does not turn the pump off when the water is emptied from the boat. This drains the battery. Very disappointing.

I had to order another one the first one failed after two weeks
The item seem to work fine, but then it failed after less than two weeks. I had to re-order another one hoping this one doesn’t fail as well.

High hopes disappointing results
This looked like a fantastic solution, unfortunately it didn’t work as well as I’d hoped. Installed this switch less than a year ago and it has already failed. It occasionally failed to shut off the pump and It requires a magnetic breaker instead of a fuse, which further increases the cost of installation. Very disappointing for what I thought was a premium brand.

Whale schakelaar - prima investering
Het juiste product om mijn 18 V dompelpomp van Kärcher automatisch te laten functioneren. Eenvoudig aan te sluiten en werkt feilloos. Snelle en adequate levering. Al bij al een prima investering.

Niveauschalter ohne Schwimmer
Das Ding ist eine wahre Freude! Als berührungsloser Niveauschalter funktioniert es in jeder Situation, Dreck kann ihm nichts anhaben.
