Reliable switch Not exactly cheap, but the first float switch I know of that works reliably even when tilted.

Functionary like he should I initially ordered the Ultima Switch. However, it was defective, and after reading a bit online, it seems many people have the same problem with the Ultima Switch: it doesn't turn the pump off again. That's why I bought this electromagnetic switch, which does what it's supposed to.

Unfortunately, it wasn't working when I arrived in Martinique...
Just bad luck, the 0.9% defective one worked for me, the original one lasted 22 years.
