How do the bimetallic strips in thermostats work? - bimetallic strips
The bi-metal strip consists of two long, thin strips of metal together.
When metal is heated or cooled, it expands and contracts. However, different metals expand and contract different amounts. One of the two metals expand much when heated and cooled. The other, not both.
This means that if the tape is heated, bends, stretches at first more than the others, is opposed to the other party expansion.
The temperature can be calibrated to the sum of the curves of the Gaza Strip.
However, these strips in the shape of the coil had little space. But the principle is the same. One side of the expansion. The others are less. The metal "Bends" or recreational or loops or whatever. The temperature is determined by the dynamics.

They are activated in accordance with their thermal expansion coefficients of the switch when it is colder than the temperature graded.
What he said.
Two strips with different thermal expansion coefficients are compiled in a way so that you can get a more accurate temperature measurement.
one side is growing faster than the other side, so that the band bending
(read the answers .... do not know how to say, lol)
(two, such as binding ..... two bands will allow fixed butt? Po)
