A relay is an electrically operated switch that uses an electromagnet to open or close a circuit. When current flows through the coil of the relay, it creates a magnetic field that attracts a movable armature, causing the contacts to either open or close. The AG alloy contact relay uses silver alloy for its contacts, a crucial component that ensures the relay can handle electrical currents with minimal wear and tear.

    The AG alloy used in the contacts is typically a combination of silver and other metals like copper or palladium. The exact composition of the alloy can vary depending on the specific requirements of the application, such as resistance to corrosion, oxidation, or high temperatures. The silver alloy contacts are highly conductive, making them an ideal choice for relays that need to transmit large currents without significant voltage drops.
