As pictured (float down) they are NC (normally closed)

They work. As they repeatedly warn you, they do not handle large loads - I used mine as a pulldown to an arduino pin and they are fine for that. They'd be fine for switching a 20mA LED, piezo buzzer or triggering a transistor, too. More than that and you're probably pushing your luck with the little magnetic reed switch inside. They claim you can drive a *small* relay with one - I wouldn't, personally. If you need that, a ULN2003 can drive the relay and this can drive the ULN2003; problem solved.
Mine was NC with the float down. That's of no consequence when using them to trigger arduino inputs, since you decide what on and off mean in software. For some other applications you might need to install them upside down to get them to turn on when water is present and off otherwise.

works perfect thought its cheap stainless steel so keep it away from any corrosive environments
Don't use contacts for over 100mA, DO NOT directly drive solenoid with float switch. SENSE ONLY!
Troy, just troy.✓ Verified Purchase•August 24, 2023
Not reliable: 400mA through contacts keeps it from opening when bulb lifts. Smaller sense current of 10mA through contacts is reliable. Added blocking diode + capacitor snubber across contacts and solenoid valve to prevent arcing to no avail. Resistance is still under 1 ohm when closed, so, again, as sensing with low current they work just fine.
Don't use this to drive a heavy duty coil relay or solenoid directly. Only as an input to a solid state relay or micro controller. Otherwise, the switch won't open. I suspect it's a 300mA reed switch and they are saying it can be used for up to half an amp. But after 2 hours at 0.4A, it reliable does NOT open when float lifts. Purchased two of these and both have same issue.
I now only use them to sense with small current to drive SSR and haven't had an issue.

AAAAA
Silvia now reports on low water level
Felix Schweizer✓ Verified Purchase•August 5, 2023
I used this level together with a button battery and an LED to indicate when water levels in the tank of my Rancillio Silvia Espresso machine drop low. Works like a charm! No more aborted espresso draws and waste of precious beans.
