Gulfmew 1 Pack SS3 Pan Float Switch with Condensate Overflow Detection, SS3 Condensate Overflow Switch, Water Leak Detector for HVAC System Drain Pans, Install on Primary and Auxiliary Drain Pans

It works as I wanted it to.

Used to shut down HVAC heat pump drip pan. Just clip on side of pad like a ballpoint pen, connect with wire nuts or crimp on connectors, and then set the depth inn the pan! If you’re not sure which wire to cut, get help

Works well

Nice but not bright enough for puzzle use

Good pan sensors, delivered quicker than I could go in to town to supply house used to replace critter chewed sensor. Plug and play.

Works fine as a spa water level switch.

0 stars should be an option. This is absolute junk. I'm glad I checked on it. The switch was totally submerged, with the float all the way up. But there was still continuity in the circuit! It didn't open the circuit. It didn't turn anything off. It didn't do anything.

Used on carrier 10 ton package unit. Works great.
