Q: What does "protected" mean in the context of this switch?

A: The "protected" designation refers to the switch's design, which includes protective housing around the internal contacts. This helps prevent accidental activation and shields the internal mechanism from dust, debris, and minor impacts, contributing to a longer operational lifespan.
