NATO Supply Class 5930 is a classification for switches within NATO Supply Group 59, which is dedicated to electrical and electronic equipment components.

Switches are devices that are used to control the flow of electricity within a circuit. They can be manually operated or automated, and are commonly used in various electrical and electronic systems.

In the context of NATO Supply Class 5930, switches can include a wide range of devices such as toggle switches, push-button switches, rotary switches, slide switches, and more. These switches can be used in different applications, including but not limited to, military equipment, communication systems, power distribution systems, and electronic devices.

The purpose of the NATO Supply Classification System is to provide a standardized method for categorizing and identifying items used by NATO member countries. This classification system helps in the procurement, inventory management, and logistics support of military equipment and supplies.

By categorizing switches under NATO Supply Class 5930, it becomes easier for NATO member countries to identify, procure, and maintain the necessary switches for their electrical and electronic equipment components.
