UL 61058-2-3:2020 is a technical standard for switches, used in electrical appliances and electronic equipment. This standard sets forth the requirements and test methods for switches with a rated voltage not exceeding 480 V and a rated current not exceeding 63 A, intended to be connected to circuits of nominal voltage not exceeding 3,000 V.
Scope and Application
The scope of UL 61058-2-3:2020 covers switches used in various industries such as domestic appliances, automotive, industrial machinery, telecommunications, and more. It applies to switches that are manually operated, mechanically operated, or remotely controlled.
This standard is intended to ensure the safety and functionality of switches by establishing minimum requirements for their construction, performance, and electrical characteristics. It also provides guidance on marking and instructions for installation, operation, and maintenance.
Key Requirements and Test Methods
UL 61058-2-3:2020 specifies several key requirements that switches must meet to comply with the standard. Some of these requirements include:
Contact Opening and Closing: The switch should open and close contacts effectively under normal conditions and withstand specified levels of mechanical stress.
Temperature Rise: The switch should not exhibit excessive temperature rise during normal operation to prevent overheating or damage to the surrounding components.
Dielectric Strength: The switch should provide adequate electric insulation between its parts to prevent electrical shock hazards.
Endurance Testing: The switch's durability and reliability should be evaluated by subjecting it to repeated mechanical operations over an extended period.
Environmental Conditions: The switch should be tested to withstand various environmental conditions, including temperature, humidity, and vibration.
Conclusion
UL 61058-2-3:2020 plays a critical role in ensuring the safety and performance of switches used in electrical appliances and electronic equipment. By following this standard, manufacturers can produce reliable switches that meet the necessary requirements for different industries. It ultimately protects consumers from potential hazards and promotes uniformity and compatibility across various electrical systems.
