What is UL 61058-2-812020?

UL 61058-2-812020 is a standard in the electrical industry that specifies safety requirements for switches for appliances. This standard, developed by Underwriters Laboratories (UL), ensures that switches used in domestic and commercial appliances meet specific criteria to ensure user safety.

Understanding the Scope of UL 61058-2-812020

The scope of UL 61058-2-812020 covers switches with rated voltages not exceeding 600 V and rated currents not exceeding 63 A. It includes various types of switches, such as toggle switches, rotary switches, rocker switches, slide switches, and push-button switches.

The standard covers both manually operated switches and electronically controlled switches commonly found in different appliances, including household appliances like refrigerators, washers, and dryers, as well as commercial and industrial appliances.

Key Safety Requirements

UL 61058-2-812020 sets out specific safety requirements that switches must meet to comply with the standard. Some of the key safety requirements include:

Contact Endurance: The switch contacts must be able to withstand a specified number of operations without any adverse effects on performance or safety. This ensures that the switch remains reliable throughout its lifespan.

Temperature Rise: The switch should not undergo excessive temperature rise during normal operation. High temperatures can lead to safety hazards or impair the functionality of the switch.

Abnormal Operation: The switch must have features to prevent dangerous conditions in case of abnormal operation, such as short circuit protection or overcurrent protection.

Dielectric Strength: The switch should have adequate dielectric strength to ensure insulation between live parts and accessible parts, preventing electric shock hazards.

Compliance Certification

Appliances that incorporate switches meeting the requirements of UL 61058-2-812020 can bear the UL mark, indicating compliance with the safety standards. By incorporating UL-certified components, appliance manufacturers demonstrate their commitment to providing safe products to consumers.

It is important to note that UL 61058-2-812020 is just one of many standards that manufacturers need to comply with. Other relevant standards may cover aspects like electrical wiring, grounding, or electromagnetic compatibility.

In conclusion, UL 61058-2-812020 is a crucial standard in the electrical industry that ensures switches used in appliances meet specific safety requirements. Manufacturers must comply with this standard to guarantee user safety and earn the UL certification mark for their products.
