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.
3. Main Materials for Silver contact Points
Silver/Fine grained /silver/Silver-Nickel/Silver-Tungsten/Silver-Graphite/Silver-Cadmium Oxide/Silver-Tin Oxide/Silver Zinc Oxide etc.
