Company view
How do our thermostat switches on and off?
1. An outer dial enables you to set the temperature at which the thermostat switches on and off.
2. The dial is connected through a circuit to the temperature sensor (a bimetal strip, shown here colored red and blue), which switches an electrical circuit on and off by bending more or less.
3. The bimetal ("two metal") strip is made of two separate metal strips fastened together: a piece of brass (blue) bolted to a piece of iron (red).
4. Iron expands less than brass as it gets hotter, so the bimetal strip curves inward as the temperature rises.
5. The bimetal strip forms part of an electrical circuit (gray path). When the strip is cool, it's straight, so it acts as a bridge through which electricity can flow. The circuit is on and so is the heating. When the strip is hotter, it bends and breaks the circuit, so no electricity can flow. Now the circuit is off.
