Switches are made of plastic or bakelite because they don't conduct electricity.
Dr. Leo Baekeland made the first thermosetting plastic. He made this in the year of 1909 and it was originally called Bakelite.
Clothes hangers are usually steel, but some are made of aluminum. Construction hangers can be steel, galvanized steel, copper, or other metals.

I think is made out of hard plastic
Bakelite was a common material used for electrical switches and plugs in the past due to its insulating properties and heat resistance. However, modern switches and plugs are more commonly made from materials like plastic, rubber, or metal, depending on the specific application and required performance characteristics.
Hard to say. Plastics wasn't a big thing in the early 1900, with Bakelite - the first plastic - only having been invented in 1907. Yes - light switches were made of Bakelite. This was considered the first plastic based on a synthetic polymer which was made of phenol and formaldehyde in 1907. In additon many of the electic controls contained handles and buttons of the same materials
Handle of electrical ions are made up of plastic or bakelite because plastic are poor conductor of both heat and electricity so it is made up of plastic or Bakelite
Bakelite is a plastic made from phenol and formaldehide. It is a polymer.IUPAC name for bakelite is, polyoxybenzylmethylenglycolanhydride.
Switches are usually made of Thermo Setting Polymers. Bakelite is an example.
Older TV cases were made of a plastic called 'Bakelite'
Early telephone casings were cast or moulded using metals (copper,alloy,brass) or bakelite type plastic
Plastic does not conduct electricity.
Bakelite jewelry is basically vintage jewelry made from bakelite, the very first type of plastic that enables molding once heated. Bakelite is easily colored and can also be carved, which is why bakelite jewelry often depicts flowers and other colorful designs.
Plastic was first made in the United States in 1907, by Leo Baekeland. He invented the first synthetic plastic called Bakelite.
Bakelite is used in making electrical appliances because it has very good electrical insulating properties.
Switches are typically made of plastic because plastic is a good insulator, which helps to prevent electrical shocks. Plastic is also lightweight, durable, and cost-effective compared to metal. Additionally, plastic can be molded into various shapes and colors easily to suit different design preferences.
