Only tried a couple of them but so far they work pretty well. These were the only 10a N.C. ones I could find and it was a good price for the assortment. Like most bimetal thermal switches, they aren't super accurate but it's perfect for an additional fail-safe in addition to a thermal fuse or another type of fail-safe. The specs show that they open (turn off) at the trigger temperature listed, then they close (turn back on) once it drops to the reset temp (from memory I think roughly 25-35°C under the listed trigger temp). Always check it works before installing. Perfect for heater fail-safes. This will not replace a temperature controller for active temperature maintenance/control, in case anyone was under that impression. I would buy again.

Tested a few different temps from this set up and they all behaved differently - going back
