ISO standard Electrical Contacts for Miniature Circuit Breaker
Electrical contacts factory, more than 12 years manufacture experience, attained ISO9001-2015, work on OEM and ODM projects..
1. Introduction of the Silver Electrical Contacts
Silver contact refers to the electronic appliances when opening and closing, separation and mutual contact of intersections, because the metal conductor terminals at the instant of the contact prone to moments of fever and spark, prompting them to contact point in the process of using multiple frequency, prone to oxidation and electrolysis, so will increasing the thickness of the contact point, or manufactured polymer metal (copper and multiple) with different material, so will called silver contact.
2. Application of Silver Electrical Contacts
Silver Electrical contact mainly used small and medium-sized current contactor, starter, temperature controller, switches, etc. undercurrent contact devices, micro switches and precision instruments.
3. Main Materials for Silver Electrical Contacts
Silver, Silver-Nickel, Silver-Tungsten, Silver-Graphite, Silver Cadmium Oxide, Silver Tin Oxide, Silver Zinc Oxide, (Ag, AgNi, AgCdO, AgSnO2, AgSnO2ln2O3, AgZnO,)etc.
