What is a silver contact and where is it used?

Introduction to the characteristics of silver contacts

The silver contact refers to the point of intersection where the electronic appliances are disconnected and contacted when they are opened and closed.

Since the metal conductor terminal is prone to instantaneous heat and sparks at the moment of contact, the contact point is prone to oxidation and electrolysis in the multi-frequency process of use, so the contact point is increased and thickened, or polymer metal is used. Manufacturing (copper and silver are the most common materials), so this contact point made of polymer metal, or a point thickened with the same material is called a silver contact.

The characteristics of silver contacts are that it increases the frequency of use of the conductor, increases the contact effect, and enhances the performance of the conductor.

Silver contacts are widely used in the production of electronic appliances, such as switches, relays, and the intersection fulcrums in conductive circuits, etc., and they are mainly riveted on the terminals of various accessories by using a silver riveting machine. The main materials used for silver contacts are silver, copper, iron, aluminum, etc., which generally need to be plated with silver to enhance its conductive effect and prevent oxidation.
