First, a 'Bi-metallic Strip' consisting of two different metals, having different 'Coefficients of Expansion', fused together in a two-layer strip which is connected electrically to the kettle element power supply.
It is placed in a chamber, generally in the kettle handle, where steam from the top of the kettle can come into contact with the chamber holding the metal strip. (Not with the strip itself).
When at room temp., the electrical contacts are closed allowing current to flow to the Element when power is switched on.
When the kettle boils, steam is passed around the chamber that contains the strip, causing it to heat up.
The metal having the higher 'C of E' of the two making up the bi-metal strip, will expand more than the other, causing the strip to bend and open the contacts, thus shutting off the power.
