New Test Procedures:

UL 61058-2-2020 introduces new test procedures that are designed to ensure the safety and performance of switches under a variety of conditions. These procedures include tests for electrical continuity, insulation resistance, and voltage drop, among others.

Changes in Terminology:

The standard has been updated to reflect the latest industry trends and terminology. This includes changes in the terms used to describe different switch components, such as "current-limiting device," "main circuit breaker," and "tripping device."

Updates to Appendices:

The standard has also been updated to include updates to appendices that provide guidance on the design, testing, and inspection of switches.

Purpose of UL 61058-2-2020

The primary purpose of UL 61058-2-2020 is to provide guidance and criteria for manufacturers, testing laboratories, and regulators to evaluate switches used in various appliances, industrial equipment, and commercial devices. The standard covers a wide range of switches, including those found in household appliances, industrial equipment, and commercial devices. It sets forth specific requirements for the construction, performance, and safety aspects of switches.

Key Requirements of UL 61058-2-2020

To ensure the safety and performance of electrical switches, manufacturers must comply with the requirements of UL 61058-2-2020. The standard provides specific requirements for the construction, performance, and safety aspects of switches. Some of the key requirements of UL 61058-2-2020 include:

Electrical Contacts:

Ensure that electrical contacts are securely mounted and are free from mechanical interference.

Insulation:

Ensure that the insulation of the switch is adequate to prevent electrical currents from passing through to the switch or the user.

Current Limiting Devices:

Ensure that current-limiting devices are installed and functioning correctly to prevent overcurrents.

Voltage:

Ensure that the voltage handling capacity of the switch is adequate to prevent voltage surges or overloads.

Ground:

Ensure that the grounding of the switch is adequate to prevent electrical hazards.

Fault Tolerance:

Ensure that the switch is designed to.
