What is UL 61058-2-2020?

UL 61058-2-2020 is a technical standard that specifies the safety requirements for electronic switches used in appliances. It is part of a series of standards developed by Underwriters Laboratories (UL), an independent global safety science company.

Scope and Application

This standard applies to switches with declared voltage ratings of not more than 600 V AC, and/or not more than 250 V DC, used in household and similar appliances. It covers various types of switches, including toggle switches, rocker switches, rotary switches, and push-button switches.

The purpose of UL 61058-2-2020 is to ensure the safe operation of these switches, minimizing potential hazards such as electric shock, fire, or mechanical failures. Compliance with this standard is important for manufacturers, regulatory authorities, and consumers to ensure the quality and safety of electronic switches used in appliances.

Key Requirements and Testing

UL 61058-2-2020 sets forth specific requirements related to the construction, electrical characteristics, and performance of electronic switches. These requirements include parameters such as dielectric strength, insulation resistance, contact temperature rise, and endurance testing.

The standard also provides guidelines for marking, instructions for installation and use, and requirements for abnormal operation. It specifies various tests that should be conducted, such as durability testing, temperature-rise testing, and overload testing, to determine compliance with the safety requirements.

Benefits of Compliance

Compliance with UL 61058-2-2020 offers several benefits. Firstly, it ensures the safety of end-users by reducing the risk of electrical accidents and fires caused by faulty switches. Secondly, it enhances the reputation and credibility of manufacturers who adhere to the standard, as it demonstrates their commitment to producing safe and reliable electronic switches.

Furthermore, compliance with UL standards may be mandatory for market access in certain countries or regions. In many cases, appliances containing UL-certified components are more likely to be accepted and approved by regulatory authorities. Compliance also helps manufacturers avoid costly product recalls, legal issues, and damage to their brand reputation.
