Bakelite is used for making electrical switches because it is a poor conductor of heat and electricity.
Why is bakelite used?
Bakelite due to its high resistance to electricity and heat is used in automotive components and industrial applications. Due to its excellent insulating properties it is used for making switches and other electrical appliances. It is also used to make various kitchenware products like frying pans etc.
Why bakelite is used for making plugs sockets and electrical fittings?
bakelite has high heat resistant property which makes it a poor conductor of heat and electricity.it is used for making electrical switches because it high heat resistance property protects us from electric shocks.
Which plastic is used for making electrical switches and why?
Bakelite is a thermosetting plastic which is a poor conductor of heat and electricity. It is used to make electrical switches and handles of utensils.
Which plastic is used to make switches?
PVC is widely used to insulate electric wiring, while thermosets (which can withstand high temperatures) are used for switches, light fittings and handles.
Why was Bakelite discontinued?
Bakelite applications in conservation were discontinued in the 1940s because of certain disadvantages that soon became apparent. The lack of records and relevant information precludes any assumption on the extent of its use and in which institutions. Its discovery is attributed to the German chemist A.
What property makes Bakelite so hard?
Statement 1: Bakelite is hard and has high melting point. Statement 2: Intermolecular forces of attraction in it are H-bonding.
What would happen if we make electric switches with thermoplastics?
Answer: suppose if electric switches are made by thermoplastics it is a good conductor of heat when these are heated they lost their shape.So the electric equipment will be destroyed and may lead to electric shock.
What is the purpose of using electric switch?
Electricity and Circuits | Exercise
A switch is used to complete or break an electric circuit to use an electric appliance according our convenience. Some electrical gadgets that have switches built into them are electric lamps, cooler, washing machines, table fan, TV, radio, etc.
How electrical switches are made?
More recently and increasingly popular, switches are made of thermosetting plastic. … It is no wonder then, the material that is used for switches have to be bad conductors of electricity, like porcelain, bakelite, and thermosetting plastic. Thermoset plastic was developed in 1906 by Belgian chemist Leo Baekeland.
What are the 4 types of switches?
The types of switches are classified into four types namely:
- SPST (Single Pole Single throw)
- SPDT (single pole double throw)
- DPST (double pole, single throw)
- DPDT (double pole double throw)
Which plastic are not used to produce electrical switches?
Bakelite is a thermosetting plastic which is a poor conductor of heat and electricity.
Which metal is used for making electrical switches Why?
Bakelite is used for making electrical switches and handles of cookware because it is a poor conductor of heat as well as electricity.
