Plastic does not conduct electricity.
Switches are made of plastic or bakelite because they don't conduct electricity.
Modern light switches are made from plastic, copper, and (maybe) coiled steel springs.
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.
Such switches need to have at least some parts that are non-conducting.
Switches are typically made of plastic, metal contacts, and a spring mechanism. The plastic housing holds the components in place while the metal contacts make and break connections to allow or interrupt the flow of electrical current. The spring mechanism provides the tactile feedback and resistance when the switch is pressed.
Light switches are typically made from thermoplastic materials, with polycarbonate and nylon being the most common choices. These plastics are favored for their durability, impact resistance, and electrical insulation properties. Additionally, some switches may use a combination of materials, including metal components for the internal mechanisms. Overall, the choice of plastic ensures safety and functionality in everyday use.
They are not made of just plastic, though. They also contain metal. The metal parts move towards or away from one another to make or break the circuit, while the plastic keeps them in place without itself conducting current.
Some light switches do have a brushed metal fascia but this is laid on a plastic substrate and the plate is earthed to prevent any chance of electric shock.They are not permitted in bathrooms.
Keyboards are typically made from a combination of plastic, metal, and rubber components. The keys themselves are made from plastic, with symbols often printed or engraved on top. The internal mechanisms include metal plates for support and rubber dome switches for key actuation.

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.
Because when a company wants to sell something, they will always have competition with other companies selling the same product. To attract customers the company must lower their price, but if they reduce their price their profits will also be reduced. Hence, they must use a cheaper material to build and that is often plastic. And also cos they are cheap bastards, if this was my worlds, everything would be made from carbon fibre and industrial diamond and polycarbonate..! =D
