- Aug 09, 2018-

International standards: There are currently two international standardization organizations, the International Committee for Standardization (ISO) and the International Electrotechnical Commission (IEC).



National Standard: The national standard that specifies the conformity of a product or a similar product to ensure its applicability is divided into mandatory (GB) and recommended (GB/T).


For example, button switch, micro switch, rated voltage, current selection standard rated voltage is preferably: 125V, 250V (if other voltage ratings, the rated voltage should not be less than 120V) The rated current is preferably: 3A, 6A, 10A, 16A, 20A, 25A, 32A and 63A, the rated current should not be less than 6A, but the rated current of the momentary action or switch used to operate the bell, electromagnetic remote switch or delay switch can be 1A, 2A and 4A.


Key switch, micro switch, safety mandatory certification

The electrical products must be certified as CCCfor safety certification. The CCCcertification is the certification issued by the China Quality Certification Center (CQC) for manufacturers of electrical equipment. The enterprises that have obtained the certificates should conform to the national standards, and the CCCcertification is also The effective monitoring means of domestic and foreign products sold in the domestic market is also an essential pass for electrical accessory products to enter the Chinese market.
