What is UL 61058-2-2:2020?

UL 61058-2-2:2020 is a professional technical standard that is widely used in the electrical industry. It provides guidelines and specifications for the construction and performance of switches. In this article, we will explore the key aspects of UL 61058-2-2:2020 and its significance in ensuring the safety and reliability of electrical switches.

Scope and Application

The scope of UL 61058-2-2:2020 covers switches with a rated voltage not exceeding 480 V and a rated current not exceeding 63 A. It includes specific requirements for various types of switches such as manual switches, electronic switches, and mechanical switches. This standard is applicable to switches used in a wide range of electrical devices, from household appliances to industrial machinery.

Safety Requirements

UL 61058-2-2:2020 sets forth a comprehensive set of safety requirements that switches must meet to ensure reliable operation and minimize potential hazards. These requirements encompass aspects such as insulation resistance, dielectric strength, temperature rise, and protection against electric shock. By adhering to these safety requirements, manufacturers can produce switches that are safe to use and comply with industry regulations.

Performance Testing and Certification

To validate compliance with UL 61058-2-2:2020, switches undergo rigorous performance testing, including functional tests and endurance tests. Functional tests assess the performance of switches under normal operating conditions, while endurance tests evaluate their durability over an extended period of time. Once switches meet all the necessary requirements and pass the tests, they can be certified as UL 61058-2-2-compliant.
