Safety Integrity Level (SIL):

SIL 0: The switch is designed to prevent electrical hazards.

SIL 1: The switch is designed to minimize the risk of electrical hazards.

SIL 2: The switch is designed to reduce the risk of electrical hazards and minimize the risk of fire.

Environmental Stresses:

The switch must be able to withstand the environmental stresses specified in Table 1.

Performance:

The switch must meet the requirements specified in Table 2.

Compliance:

The switch must be labeled in accordance with the requirements specified in Table 3.

Conclusion:

UL 61058-2-2020 is a critical standard for the safety and performance of electrical switches. Compliance with this standard is essential for manufacturers, designers, and engineers involved in the production and development of electrical switches.
