When the bimetallic strip cools down, the metals in the strip contract at different rates due to their varying coefficients of thermal expansion. This differential contraction causes the strip to bend, with the side of the metal with higher expansion coefficient (usually the inner layer) being on the inside of the curve.

How could a bimetallic strip be used to help in every day life?
A bimetallic strip can be used as a thermometer or thermostat. The two metals expand at different rates which will make it bend. You can use this to find the temperature of an oven. When the temperature of the oven increases, the strip will curve and break the electrical contact which make the oven cool down. When the oven cools the bimetallic strip will become straight again and the electrical contact will be remade and the oven will begin to reheat again.
Can anyone explain the use of a bimetallic strip in heat regulation in an electric iron?
When the temperature of the iron increases, the bimetallic strip bends upwards. This breaks the contact between the strip and the heating coil. When the temperature falls, the bimetallic strip bends down and the contact is restored.

How does a bimetallic strip act as a switch?
It acts as a switch in thermostats because it starts curved and when it cools down enough for it to straighten up it touches another piece of metal, completing a circuit before bending again due to the heat. Hope this helped!
