What does the bimetallic strip in an electric iron do?
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!
What is the function of overload protector in refrigerator?
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.

What is a bimetallic?
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.

What temperature is required for a bimetallic strip to bend?
A bimetallic strip will bend when exposed to a temperature above its specific bending temperature, typically in the range of 100-200 degrees Celsius. The differential expansion of the two metals in the strip causes it to bend due to the unequal expansion rates.
What is bimetallic strips used for?
Bimetallic strips were commonly used in thermostats. The two metals would expand at different rates and therefore bend. When a bimetallic strip, made of iron and brass [or any other metals] is heated, both metals expand differently, causing the bimetallic strip to bend. These bimetallic strips are used in fire alarms. The heat of the fire, causes the brass and iron strips to expand, ultimately resulting in the bending of the bimetallic strip, which on bending touches the screw adjacent to it, thus completing the circuit. Once the circuit is complete, the bell begins to ring. Thus the brass bends more than the steel, but on cooling, contracts more than the steel, thus causing the bimetallic strip to bend in the opposite direction.
Appliances bimetallic strips are used in?
Bimetallic strips are used in appliances for temperature control and safety mechanisms. When the bimetallic strip is heated, the two metals with different coefficients of thermal expansion expand at different rates, causing the strip to bend. This bending action can be used to open or close electrical circuits, regulating the temperature or activating safety features in appliances such as irons, thermostats, and circuit breakers.
Are there any other uses for the expansion and contraction of matter?
Yes, expansion and contraction of matter are used in various practical applications such as bimetallic strips in thermostats, thermometers, and in certain types of mechanical relays. These mechanisms utilize the different rates of expansion and contraction of two materials to measure temperature or to act as switches in electrical circuits.

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.
Which material can be used as bimetallic strip?
You may use any two metals which have different thermal expansion properties. Steel and brass are commonly used because of cheapness. There is not even a need for them to be metals - you could bond two glasses of different thermal properties, and these would bend as well.
