For medical pendant, what is the difference between dry part and wet part?

In medical pendants, the dry part typically refers to the electrical components and wiring that do not come into contact with any liquids or moisture. The wet part, on the other hand, refers to the portion of the pendant that is designed to resist water or other liquids, such as the casing that houses the electrical components or the buttons that are used to activate the pendant.

The distinction between the dry and wet parts of a medical pendant is important because it helps ensure that the electrical components are protected from damage due to exposure to moisture or liquids, which could in turn compromise the safety and function of the pendant.
