Which box is typically used for switches?

The utility box is specifically designed to house electrical connections and devices, including switches. Its structure allows for easy installation of switches while providing sufficient space for wiring and connections. Utility boxes can accommodate various types of switches and often come with features that facilitate mounting to walls and ceilings.

In contrast, splice boxes are generally used for the purpose of joining or splicing wires rather than housing electrical devices. Full boxes usually refer to larger enclosures that may be used for more extensive wiring runs or installations, such as junction boxes, and do not typically serve as the primary location for switches. Square boxes can be used for switches but are more commonly associated with general wiring applications, providing a basic enclosure without the specialized design elements that utility boxes offer for switches.

Thus, the utility box stands out as the most appropriate choice for housing switches due to its specific design features and suitability for this application.
