What type of switches are required when the space between door and window casing is too small for a 2-gang plate?

Combination switches are designed to accommodate scenarios in tight spaces where a standard two-gang switch plate cannot fit. They typically combine two functionalities into one single unit, allowing for more efficient use of space without sacrificing control over multiple circuits. For instance, a combination switch might integrate a regular toggle switch with a dimmer or an outlet, providing two functionalities in a single gang space.

This approach is particularly useful in residential applications where aesthetic considerations and space limitations need to be balanced, especially around door and window casings. The design of combination switches allows for cleaner installations without cluttering the wall with multiple switch plates. In contrast, standard single switches, triple switches, and dimmer switches don't specifically provide the compact solution needed for tight spaces in this scenario.
