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.
A switch is a means of making (on) or breaking (off) an electrical circuit.
Clay
The radiation comes from the material used.
