What metal is preferred for use in relay contacts due to its conductivity and durability?

Silver is preferred for use in relay contacts because it has excellent conductivity, which is crucial for ensuring efficient electrical performance in relays. Its low contact resistance enhances the reliability of electrical connections, allowing for minimal energy loss. Silver also exhibits good durability and resistance to oxidation, which can degrade contact performance over time. This makes it suitable for applications where consistent and reliable electrical connections are essential.

In addition to these characteristics, silver's ability to maintain its conductive properties even under varying temperatures and conditions makes it a strong choice for relay contacts. While other metals may offer good conductivity, silver strikes the best balance of conductivity, durability, and performance, especially in high-current applications.
