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.

What household appliance could a bimetallic strip be used?
A bimetallic strip could be used in a thermostat, where it can bend and complete or break an electrical circuit to regulate temperature.
Why do some thermostats have a spiral shaped bimetallic strip?
The spiral shape allows for more expansion and contraction of the bimetallic strip, providing greater sensitivity to temperature changes compared to a straight strip. This design helps the thermostat respond more quickly and accurately to fluctuations in temperature, making it more precise in regulating heating and cooling systems.
What is the use of a bimetallic strip in a thermostat?
The 2 metals have different coefficients of expansion so when the strip heats up it bends. This bending is arranged to separate an electrical connection so that the electrical power causing the heating is switched off, and then back on again when things cool back down slightly.
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.
The element in a thermostat that is sensitive to temperature changes is what?
The element in a thermostat that is sensitive to temperature changes is typically a bimetallic strip. This strip is made up of two different metals that expand and contract at different rates in response to temperature variations, causing the strip to bend and activate the thermostat's switch.

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.
How much does a bimetallic strip cost?
The cost of a bimetallic strip can vary depending on the size, material, and manufacturer. On average, a bimetallic strip can range from a few dollars to tens of dollars.
