UL 61058-2-29:2020, also known as "Switches for appliances - Part 2-29: Particular requirements for cord switches," is a technical standard developed by Underwriters Laboratories (UL) that sets forth safety requirements for cord switches used in various electrical appliances. This standard specifies the constructional and performance criteria that cord switches must meet in order to ensure safe and reliable operation.
Why is UL 61058-2-29:2020 important?
Cord switches are commonly used in appliances where direct control of power supply is required, such as lamps, fans, and other household devices. UL 61058-2-29:2020 plays a crucial role in ensuring the safety of these appliances and preventing potential hazards. Compliance with this standard helps manufacturers design and produce cord switches that meet stringent safety requirements, reducing the risk of electrical shocks, fires, and other accidents.
Main requirements of UL 61058-2-29:2020
UL 61058-2-29:2020 lays down specific requirements for various aspects of cord switches, including their mechanical strength, electrical insulation, contact resistance, temperature rise, endurance, and resistance to excessive voltage. The standard addresses both normal and abnormal operating conditions, ensuring that cord switches can withstand expected stresses and maintain their integrity under different circumstances.
Compliance and certification
Manufacturers of appliances utilizing cord switches must ensure that their products comply with UL 61058-2-29:2020. Compliance testing involves rigorous evaluation of the cord switches, including sample inspection, function verification, dielectric strength testing, and assessment of temperature rise and other performance parameters. Products that pass the testing can be certified as meeting the requirements of UL 61058-2-29:2020, allowing them to bear the UL mark, a recognized symbol of product safety.
