Key Changes in UL 61058-2-2020:

Key changes in UL 61058-2-2020 include:

Increased Focus on Safety:

UL 61058-2-2020 places a greater emphasis on safety features, such as circuit breaker protection, over-current protection, and thermal overload. These features are intended to ensure the safety of users and minimize the risk of electrical fires or injuries.

Emphasis on Environmental Stresses:

The standard also emphasizes environmental stress testing, which is critical for switches used in harsh environments. The testing procedures have been updated to reflect the impact of extreme temperatures, humidity, and other environmental factors on switch performance and safety.

Changes in Test Requirements:

The standard has been updated to reflect the latest trends in testing and evaluation. For example, the standard now requires switches to undergo a series of tests, including thermal cycling, short-circuit testing, and voltage surges. These tests are designed to ensure switches perform as expected under a wide range of operating conditions.

New Requirements for Switches with Integrated Circuitry:

In recent years, there has been a significant increase in the use of integrated circuitry (IC) in switches. To address this, the standard has been updated to include new requirements for switches with integrated circuitry. These requirements are intended to ensure the safety and performance of the switches and minimize the risk of electrical fires or injuries.

Key Requirements of UL 61058-2-2020:

To ensure compliance with the UL 61058-2-2020 standard, manufacturers must follow these key requirements:

The switch shall have an effective thermal coefficient of thermal expansion (CTE) of not more than 25 ppm.

The switch shall have a thermal conductivity of not more than 10 w/cm.

The switch shall have a maximum allowable voltage (MAV) of not more than 125 V.

The switch shall have a maximum allowable current (MAAC) of not more than 50 A.

The switch shall have a thermal cycling life of not less than 1, 000 cycles at 25°C.

The switch shall have a short-circuit voltage (SCV) of not less than 20 V.

The switch shall have a over-current protection voltage (OCPV) of not less than.
