Which is true about the use of switch boxes?

Switch boxes serve multiple purposes in electrical installations, and one of their key functions is indeed to house electrical contacts. This capability allows for the integration of various components, such as switches and electrical connectors, within a single enclosure. It is important to note that while switches are the primary components typically contained in these boxes, they can also accommodate other elements that facilitate electrical connections and circuit management.

In contrast to the other options, switch boxes are not limited to housing only switches, nor do they have to be positioned specifically near a power source. They can be installed in various locations throughout a home or building where electrical connections are needed. Additionally, while many switch boxes are commonly associated with lighting controls, their use is not restricted solely to lighting applications; they can support other electrical circuits as well. This versatility makes them essential for a wide range of electrical tasks.
