1. Introduction of Silver contact Points

Silver contact points also called a contact tip, button or terminals. It is an electrical circuit component found in electrical switches, relays and breakers. It is composed of two pieces of electrically conductive metal that pass electrical current or insulate when the gap between them is closed or open. The gap must be an insulating medium of air, vacuum, oil, SF₆ or other electrically insulating fluid



 

2. Application of Silver contact Points

Silver contact points used for high-voltage switches, electro-processed electrodes, and microelectronic materials.  As parts and components, they are widely used in aerospace, aviation, electronics, power, metallurgy, machinery, sports equipment and other industries etc.
