What determines whether a toggle switch is classified as a Category 1 or Category 2 switch as defined by United Laboratories, Inc.? How can you tell by looking at a switch if it is Category 1 or 2?

Category 1 switches can be used for AC and DC circuits. Category 2 switches are for AC circuits only. While the Category 1 switches are not usually marked explicitly as “AC/DC”, a Category 2 switch will always be marked as “AC” in addition to the current and voltage ratings.
