Why is plastic suitable for making electrical switches?
Electrical plugs are made up of plastic because plastic protects people from electricity. As we know that plastic is an electrical insulator readily available and cheap. So as to make the plugs shock free, they are made up of plastic.
How is a switch constructed?
A switch can be constructed with any mechanism bringing two conductors into contact with each other in a controlled manner. This can be as simple as allowing two copper wires to touch each other by the motion of a lever, or by directly pushing two metal strips into contact.

An iron piece is a good conductor of electricity and the rest of the options are bad conductors. Hence, the iron piece can be used as a switch in a circuit.
Why is a switch made of insulating material?
Hint: Electrical switches are made of insulating materials, like thermoplastic. And it is the property of insulators to not allow electricity to pass through them. Hence, even if we touch electrical switches with bare hands, we will not get shock, cause the switch blocks the electricity to reach up to us.

What are switches made of?
Switches are generally made from different grades of plastic but you can also get metal switches. Light switches for example are made from modern plastics such as polycarbonate or fire resistant ABS.
What are the different types of switches?
A push button switch is normally used for applications like start and stop buttons, reset buttons and control buttons. Most of the time the buttons are made from plastic or metal as they are normally in areas where they made need to be water resistant or safe for human interaction. A push button switch has two states – on or off and is used for an action on a piece of equipment or in a process.
What is a switch?
A switch is an electrical component that connects or disconnects the conducting path in a electrical circuit. A switch is made up from electrical contacts, when the contacts are touching they allow current to pass through them and when they are separated no current can pass through them. On the back of switches normally open (NO) or normally closed (NC) contact blocks can be fitted which allow current to flow when they change states.
Who invented switches?
The first switch was invented in 1884 by John Henry Holmes in Newcastle upon Tyne, Great Britain. Since then switches have been used extensively in industry and on domestic appliances.
How can switches fail?
Switches can fail for a number of different reason. We will take a look at some of the most common causes why:
Why are switches made of plastic?
Electric plugs and switches are made of plastics because they are more safer than other materials like iron, copper etc which conduct electricity which is very dangerous while switching plugs so switches and plugs are made of plastics.

How does a multi position switch work?
The volume knob on a stereo works in a similar way. Multi-position switches work in almost the same way as dimmer switches except that the resistance of the circuit can only be changed between a few set values. Multi-position switches are typically used on appliances with motors or fans.
What is the first plastic used in electrical circuits?
The first true plastic material used for the housing of electrical switches and electrical outlets was an insulator called Bakelite, invented in 1909 by engineer and chemist Leo Hendrik Baekeland. Today, material and chemical engineers continue to design and develop specialty materials that can be used for many different types of electrical device parts, both for conducting and insulating.
How does electricity flow through objects?
Remind students that electricity flows more easily through some objects than others. The materials that electrons can move through are called conductors. The atoms in a conductor have loosely-attached electrons, so a negative charge buildup pushes electrons through the material. Electrons in metals are loosely attached to the atom, so metals are conductors. If the electrons in a material are tightly attached to the atoms and cannot be forced to move from one atom to another, no electricity flows. These materials are called insulators. Some examples of insulators include rock, wood, plastic, glass, cloth, and air.
How to test a switch?
To create and test a switch, lay a test object across the two nails (or thumbtacks) to complete (close) the circuit (see Figure 4). If the light bulb lights up, the circuit is closed, current flows and the object works as a switch (conductor). If the bulb does not light up, the object does not make a good switch.
