Why a kettle clicks off at the boil

Patterns Revealed

That "click" is the kettle's hidden switch snapping off at the boil ⚡🔊
Steam travels through a tiny channel to a bimetal strip, and heat makes it snap 🫧
That snap trips the switch and cuts power. If steam can not reach it, the kettle may not shut off .
Bonus safety: boil-dry protection helps stop scorching when the kettle is empty 🔒✅
Check your kettle type at home and see what shut-off it uses.
