Bimetallic Strips

Bimetallic strips is a 2 joined metal that mesh closely to become an union.
Bimetallic strips will expand also under hot condition and contract under cold condition, however since bimetallic strips contain 2 metals, which will not expand / contract as same amount one another, they will bend according to its linear coefficient of thermal expansion.
This characteristics is very useful for electric used (mostly Mini Circuit Breaker), because they can react if there is an overheating. (Try to figure out where the bimetallic strip is).
