The switch contains a sandwich strip of 2 metals with two different coefficients of thermal expansion. The dial you would turn to control the temperature modifies the resistance of the circuit - thus current (or would be set digitally nowadays). When the desired temperature has been reached, one of the metals stretches more than the other. The metal sandwich curls, thus disconnecting the contact of the switch.

Why are bimetallic strips used in thermostats?
The two metals chosen for the bimetallic strip have different modulii of thermal expansion, The bimetallic strip bends as the temperature changes and so the strip can be used to activate relays or other electronic switches and so work as a thermostat.
Why do some thermostats have a spiral shaped bimetallic strip?
That is what makes the thermostat works, the two different metals expand and contract with the temperature and trigger the heat or air
What is bimetallic strip made of?
A bimetallic strip is made out of steel and iron
What is a bimetallic strip and where can it be used?
A bimetallic strip is a strip with two metals bonded together. It can be found in thermostats
How is a bimetallic strip used in a thermostat?
A bimetallic strip is used in a thermostat, by concealing it inside. When the temperature goes up, the bimetallic strip expands, and turns on the circuit for the AC/compressor ,to make the temperature cooler inside wherever the thermostat is.Two metal strips of differing thermal expansion are bonded together. Because the expansion is different the metals expand by different amounts. When heated the strip therefore has to bend, the one with the greater expansion on the outside of the curvature. As the strip bends it can either make or break a circuit contact depending on the configuration of the circuit, switching on of off the current. The reverse is true when the strip cools again.
