  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.   Main Materials:   Face material : Ag,AgNi,AgCdO,AgSnO2,AgZnO Base material : Cu,CuNI    (1)For a less than 32 amp circuit load, Rivets are often made from AgCdO (12) and AgNi (10)
(2)For an over 32 amp (32 amp included) circuit load, contact tips are made from AgCdO(15) or environment-friendly AgSnO2 and AgSnO2In2O3 for RoHS in sheets. In some cases, AgCdO(12) sheet is used.     Dimension specification   All dimensions are according to customer's requirements
