I imagine it’s a combination of a thermometer plus the bi-metallic switch mechanism to prevent the kettle from boiling dry, with the assumption that you’ll generally just be boiling water near sea level in them. I wonder if the nicer ones have like a calibration mode or something where you can adjust the temperature setting for different altitudes though 🤔
Oh neat, how do those kettles that have a temperature selection thingy for different kinds of tea work then?
