Work as they should.
I used these to control some 12 volt fans I added to my every fridge. They work perfectly.

Blueflame gas heater fan control replacement
The stock bimetal switch failed in my garage blueflame gas heater, rendering the fan inoperable. This switch replaced the OEM item, works great. The mounting was different but drilling a 1/8" hole for a sheet metal screw was simple. Always remember to disconnect power before doing electrical wiring. If in doubt, consult a pro.

Check the pin size!
Be sure to check the pin size of the device you’re wanting to replace. This replacement item’s pin size was larger than mine. I was totally unaware that pin size could vary.
