What is UL 61058-2-9:2020?

The UL 61058-2-9:2020 is a technical standard that sets the requirements for electronic switches used in appliances. It provides guidelines for the safety, reliability, and performance of these switches, ensuring they meet industry standards.

Purpose and Scope

The purpose of UL 61058-2-9:2020 is to establish uniform testing criteria for electronic switches. It covers various types of switches, such as push-button switches, slide switches, rocker switches, and rotary switches. The standard ensures that these switches can handle the electrical and mechanical stresses encountered during normal operation.

UL 61058-2-9:2020 applies to switches with a rated voltage not exceeding 480 V AC or DC and a rated current not exceeding 63 A. It also covers switches used in control circuits with voltages up to 500 V AC or DC.

Key Requirements

One of the key requirements of UL 61058-2-9:2020 is the insulation resistance test. This test ensures that the switch maintains adequate isolation between its live components and exposed conductive parts. It verifies that the switch can withstand high voltages without causing any safety hazards.

The standard also includes tests for temperature rise, mechanical endurance, electrical endurance, and dielectric strength. These tests assess the switch's performance under different conditions, including continuous operation, overload, and short-circuit situations. They help determine if the switch can withstand the demands of its intended application.

Additionally, UL 61058-2-9:2020 specifies requirements for marking, construction, and protection against electric shock. This ensures that users can identify the switch's ratings, installation instructions, and precautions to take during use.

Compliance and Benefits

Manufacturers who comply with UL 61058-2-9:2020 demonstrate their commitment to producing safe and reliable switches. Compliance with this standard can help build trust with consumers and regulatory authorities. It also ensures that switches meet quality standards, reducing the risk of malfunctions or accidents.

For consumers, using switches that adhere to UL 61058-2-9:2020 provides peace of mind, knowing that the switches have undergone rigorous testing. They can be confident in the switches' performance, durability, and safety features.
