Contact material knowledge

AgNi+ gold plating, AgPd: suitable for small load, signal relay contact common materials;

AgNi: small and medium resistive load (steady current ≤12A, impulse current ≤25A);

AgCdO: resistive load, inductive load (steady current ≤30A, impulse current ≤50A), have been RoHS
