It is used as a thermostat.
A thermostat is a device used to control the temperature of any equipment, in this case an electric iron.
Two little strips of different types of metals are welded or brazed together. These little strips will be mounted inside the the iron near to the hot plate, held down just at one side.
An electrical contact will join the bimetallic strip into the electrical circuit of the iron. Another little flat metal plate will be mounted near the free end of the bimetallic strip. This little fixed plate will touch the free end of the bimetallic strip.
So now you turn the iron on. The irons' hot plate heats up. The bimetallic plate heats up too as it is close to the hot plate.
Ok, now is the clever bit someone once thought out. The two strips of metal heat up and expand. As the properties of the metals are different they will expand at different amounts. As the two strips are stuck together the bimetallic strip will bend.
When it bends it will eventually bend away from the fixed plate. Assuming its been installed with the bimetallic strip the right way around! because the strip will bend to the side which has the metal that expands less. When it no longer touches the plate the circuit will turn off. And hence the power is turned off to the iron.
So how come that dial makes the iron hotter or less hot? When you are twisting the dial you are actually squeezing some tension into the bimetallic strip so that it will have to get hotter before it will bend away from the contact and hence break the circuit.
Thats the idea!

How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
How could a bimetallic strip perform a practical task in life?
bimetal stip is next to the contacts it make your oven,iron and air conditions unit work that is when ever the contacts touch from how high you put it and it heat up and the iron and brass bends
What is a bimetallic coin?
A bimetallic strip is often used in thermostats because it is quite simple to make and responds predictably to changes in temperature. The bimetallic strip is pretty much what it sounds like - a strip made from two metals. Inthermostatsit is common to make one side out of steel and the other out of copper - then bond them together. they are formed into a curving spiral. Different metals have different coefficients of thermal expansion so as the temperature changes, the spiral strip either curls up or uncurls as one side expands or contracts more than the other. The control isattachedto one end of the strip so that as it curls or uncurls, it rotates the control.Sometimes the control is a simple mercury switch that closes a contact whenrotatedone way and opens the contact when rotated the other. Sometimes one end is attached to a power source and the other end is connected to an electric contact, which moves as the strip curls and uncurls.You can also attach it to a pointer and have it point to temperatures on a dial.
What would use more volts an electric razor and electric iron?
Electric Iron by far.
Any 5 gadgets in which bimetallic strip is used?
They're all thermostats of on kind or another: home, car, stove, hot-water heater,
What uses bimetallic strip?
Appliances like electric iron, which need a cut off from the electric current from time to time as the appliance is heated adequately, use bimetallic strip for this.
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 do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
What is bimetallic strip made of?
A bimetallic strip is typically made of two different metals fused together, such as brass and steel or copper and iron. These metals have different coefficients of thermal expansion, causing the strip to bend when exposed to temperature changes.
Can we use bimetallic strip in iron box?
yes, in automated iron boxes
What happens to the bimetallic strip when the iron is hot?
When the iron is hot, the bimetallic strip will bend towards the iron due to differential expansion of the two metals in the strip. This bending occurs because the metal with higher thermal expansion coefficient will expand more, causing the strip to curve towards that side.
What happens when bimetallic strip is heated?
The bimetallic strip bends.
Which two metals are used in bimetallic strip in a tube light starter?
Bimetallic strips used in tube light starters typically consist of nickel and iron. These metals are chosen for their differing coefficients of thermal expansion, which allows the strip to bend when heated by the electric current passing through the starter.
What way does a bimetallic strip bend with iron and brass?
When heated, a bimetallic strip made of iron and brass will bend towards the brass side due to the different coefficients of thermal expansion of the two metals. This is because brass expands more than iron when heated, causing the strip to curve towards the side with greater expansion.
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.
How does bimetallic work in an electric iron?
A bimetallic strip is a strip made from 2 different metals. It is designed to bend one way if it is warm and the other way if it is cold. The hotter it gets, the more it bends. In any thermostat, the electrical contacts bend apart as the target temperature is reached. The only difference between a heating thermostat and a cooling thermostat is which side of the bimetallic strip faces the other contact. In a heating appliance, the thermostat knob turns a screw to add resistance to the motion of the contacts so they must get hotter to separate as the screw is tightened. So the tighter the screw is turned, the hotter the appliance is allowed to get before the contacts separate.
