Metals are actually good conductors of heat and electricity.
Plastics are actually weak conductor of you can say plastic as an insulator.
This means that any articles like switches if made up with metals will allow transfer of electricity through it. Hence, if a person will even touch these articles it will give shock to him/her.
Hence, making switches with plastics will not allow any electricity to come in contact with the person to harm the person.
