International switch safety standards & information
Safety standards represent the minimum standards that are required from devices and components to prevent accidents and protect consumers who use electric devices from the hazards presented by electric shock and fire.
Each country has different voltage conditions, weather conditions and safety concepts, and they all set safety standards.
If the switches are certified for the safety standards, the switches are exempt from testing when applying standard certification to devices that use those switches.
Safety Standards and Certification Bodies by Country
Safety Standards by Country
Basic Safety Standards Requirements by Region
The combustibility and ignitability of the insulation materials used in devices and components and temperature increases are regulated to emphasize the prevention of fires caused by electric devices.
The main standards are UL in the USA and CSA in Canada.
The Insulation distances and proof tracking of devices and components are regulated to emphasize the prevention of electric shock accidents caused by electric devices.
The main standards are VDE (Germany).
The proof tracking index is degree of loss of insulation when a carbonized conductive path forms on the surface of an insulation between electric poles with a difference in electric potential.
|Voltage||Accidents||Most Important Requirement|
|North America||120/240 Vac||Fire||Combustibility|
|Europe||230/400Vac||Electric Shock||Insulation Distance|
Main Safety Standards
|National Standards||－||ANSI Standards||CSA Standards||VDE Standards||Chinese National Standards: GB Standards|
|Description||Technical electric standards based on the most recent scientific technology.|
Forms the basis for standards in other countries.
|To prevent fires, standards are enforced for the sale of electric products in the USA by state and city.|
Components must also be certified.
|North American safety standards are applied and operated to prevent fire accidents, in the same way as in the USA.||Standards are designed to prevent electric shock and fires, but are not legally enforced.|
Enforcement is achieved through strict penalties.
|Items for which certification is enforced are specified, and the import and sale of uncertified items in China is prohibited.|
