Whale BE9003 Electric Field Sensor Switch, 12V or 24V, Suitable for Up to 20 Amps,Black

Pumps a lot of water for its size and water level sensors work perfectly.

This switch replaced a 15 year old switch. This new switch worked correctly for about 5 times. It turns the pump on but does not turn the pump off once the catch basin is pumped out. And now it appears there’s no support or replacement. Won’t do business with this seller anymore

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.

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.

Product works Great 👍🏻 !!

I bought this switch for my boat's bilge pump.The on and off levels are both closer and lower than a regular floating switch, but it is OK.The switch lasted few months only and now it will start the pump but never stop it unless I turn bilge pump off manualy.My other pump is using a cheaper floating switch (orange brand one) and is working for a year without problem.I won't buy it again

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!

Didn't work out of the box.

When the housing gets dirty it gets wet also the pump is ON till the motor burns. I do not recommend electronic sensor switches any more...

It works, despite I don t understand the principles

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.

Worked fine for 18 mos and then died. Only way I found out was when I had water all over the floor in the head. Not impressed.
