PVC is used to make pipes, electric cables, floorings of buildings etc. From all these given polymers, Bakelite has the highest heat resistant and it is a poor conductor of heat and electricity. Therefore, is used to make switches and plugs.
What are switches and plugs made of plastic?
Why the switches and plugs are made of plastics? Plastics are poor conductor of electricity and resistant to heat, so they do not allow the electric current to pass through them making them safe to handle. So they are used to make electric switches and plugs.
Which material is used to make plugs and switches?
(b) Electric plugs/ switches/ plug boards are saucepan is made of thermosetting plastic because it is a bad conductor of electricity.
What are electrical switches made of?
Before the current plastic switches that we are familiar with today, switches were made of porcelain. Then later, Bakelite, which was an early form of brittle plastic, made from formaldehyde and phenol. More recently and increasingly popular, switches are made of thermosetting plastic.
What plastic is a plug made from?
Although both ABS and urea-formaldehyde are used for plugs, they are in fact used for slightly different applications. In addition, ABS is used for one piece moulded plugs which prevent access by the user whereas urea-formaldehyde is used for two piece plugs that can be fitted by users.
Why are electrical sockets made from plastic?
Plastic protects people from electricity.
Why are plugs covered in plastic?
What is the purpose of the plastic 13 Amp plug pin protector? Initially it is to protect the electrical appliance from damage in transit. Packed with a plastic cased appliance the plug pins could scratch or break an appliance in transit if allowed to come into close contact with it.
Which material is used for making plug?
The materials with the lowest values of resistivity are aluminium, brass, copper and gold. All these are commonly used as conductors in practice, although clearly gold is a bit too expensive for use in a plug!
Which metal is used for making plugs and switches?
Bakelite is used for making electrical switches and handles of cookware because it is a poor conductor of heat as well as electricity.
Which material is used for making plugs and switches Class 8?
Bakelite is a poor conductor of heat and electricity. It is used for making electrical switches, electric plugs and plug boards, etc.
Which plastic is used to made electric switches?
Explanation: Bakelite is a thermosetting plastic which is a poor conductor of heat and electricity. Hence, it is used to make electrical switches and handles of utensils.
Why are switches made of plastic and not metal?
Switches are made up of plastics or bakelite and non metals because plastics are bad conductor of electricity so they will protect us from shock and metals are good conductor of electricity so they will produce shock to our body..
Which polymer is used in electrical switch?
Bakelite polymer which is used for making electrical switches and combs.
How electrical plugs are made?
A plug consists of the case or cover, three pins, a fuse and a cable grip. The case of a plug is the plastic or rubber parts that surround it. Plastic or rubber materials are used because they are good electrical insulators. The pins inside the plug are made from brass because brass is a good conductor of electricity.
