UL 61058-2-352:2020 is a global standard for safety of electrical appliances and components that are managed by electronic circuits. It specifically covers switches for electrical appliances used in household and similar purposes. The standard provides requirements and test methods to ensure the safe and reliable operation of these switches, while also considering factors such as user interface, mechanical strength, and resistance to environmental conditions.
Key Requirements of UL 61058-2-352:2020
UL 61058-2-352:2020 encompasses various key requirements that manufacturers must comply with to ensure the safety and reliability of switches used in electrical appliances. Some of these requirements include:
Contact Gap: The standard stipulates specific contact gap dimensions to ensure proper functioning of the switch and prevent accidental electrical current flow.
Insulation Resistance: Switches should demonstrate appropriate insulation resistance to avoid leakage current and reduce the risk of electric shock.
Durability: The standard sets minimum durability requirements, including a specified number of operations, to ensure the long-term reliability and performance of switches.
Temperature Resistance: Switches must withstand certain temperature ranges to ensure safe operation under typical operating conditions.
Clear Markings: The standard mandates clear and legible markings on switches to provide users with important information such as rated voltage, current, and manufacturer details.
Testing and Certification
To ensure compliance with UL 61058-2-352:2020, manufacturers need to perform various tests on their switches. These tests may include:
Dielectric Test: Verify that the insulation material used in the switch provides sufficient protection against electrical current.
Endurance Test: Subject the switch to repeated operations and evaluate its performance and durability over time.
Temperature Test: Expose the switch to different temperature conditions to confirm its resistance and stability under varying environmental factors.
Once a switch successfully meets all the requirements and passes the necessary tests, it can be certified as UL 61058-2-352 compliant. This certification signifies that the switch is safe, reliable, and suitable for use in electrical appliances.
