Almost all electronics are configured with silver. From turning out the lights to turning on your television, if it has an on/off button, it’s likely that silver is playing an important role, behind the scenes.
Its excellent electrical conductivity makes it a natural choice for everything from printed circuit boards to switches and TV screens.
Silver membrane switches, which require only a light touch, are used in buttons on televisions, telephones, microwave ovens, children’s toys and computer keyboards. These switches are highly reliable and last for millions of on/off cycles. Silver is also used in conventional switches likes those used for controlling room lights.
For printed circuit boards, used in consumer items from mobile phones to computers, silver-based inks and films are applied to composite boards to create electrical pathways. Similarly, silver-based inks produce so-called RFID tags (radio frequency identification) antennas used in hundreds of millions of products to prevent theft and allow easy inventory control. They are also used in prepaid toll road passes.
CDs, DVDs and plasma display panels are also fabricated using silver.
