How do bimetallic strips work

WebMy new toaster does this. My old one stayed down even without power. It had a bimetallic strip which would heat up and slowly bend, until it released a latch. The knob added tension to the mechanism when set lower, which triggered it earlier. A bimetallic strip is made by sandwiching two metals which expand differently when heated. This effect is used in a range of mechanical and electrical devices. Mechanical clock mechanisms are sensitive to temperature changes as each part has tiny tolerance and it leads to errors in time keeping. A bimetallic strip is used to compensate this phenomenon in the mechanism of some timepieces. The most common method is to use a bimetallic construction for the circular ri…
