Earlier switches were made of [[porcelain]] in the surface-mounted version and operated as a rotary switch with a rotary mechanism. Later, more durable [[Bakelite]] and Ebonite was used. Today they are made of modern [[plastic]]s, like polycarbonate or fire-resistant ABS. Some switches may also be manufactured from other plastics like polyamide, polypropylene or PVC but mainly limited to wire mounted switches (like night lamp switches) mainly due to reduced weight, and most such switches are not used in high power devices (mainly table lamps, table fans, some radios) mainly up to 2 amperes. In some cases, especially in hospitals and other public facilities, exposed parts of light switches are made of antimicrobial materials such as [[Copper#Antimicrobial|copper]], for [[infection control]].
