What are switch boxes joined side by side to accommodate more than one switch called?

Gang boxes are specifically designed to house multiple switches (or electrical devices) in a single enclosure to streamline wiring and provide a clean appearance in electrical installations. These boxes allow for the grouping of switches that control different fixtures or components, making it more efficient to operate various electrical systems from a single location. The term "gang" refers to the number of devices that are accommodated within the box; for example, a two-gang box can hold two switches side by side.

In contrast, connection boxes generally refer to enclosures for electrical connections without a specific focus on switches. Switch panels usually denote an assembly that includes switches but does not specifically imply multiple switches in a side-by-side configuration. Combination boxes may house a mix of devices but again do not specifically denote the side-by-side arrangement of switches. Therefore, gang boxes are the correct term when addressing a configuration of multiple switches installed together.
