Light switch faceplates are sized by gang count, with one-gang, two-gang, and three-gang options matching the number of adjacent switches, dimmers, keypads, or other Decora devices in an electrical box. Choose a faceplate with the appropriate opening layout and mounting style for the installed devices, such as a screwless design for compatible lighting controls or a faceplate that also fits standard Decora outlets.

Many light switch faceplates use a Decora design, making them compatible with standard Decora-sized switches, dimmers, and outlets. Check the faceplate and device specifications to confirm the gang configuration and fit for your installation.

Compare the gang configuration, Decora-style compatibility, and whether the faceplate uses screwless, snap-on, or magnetic mounting for the devices in the installation. Also check whether it includes a mounting or baseplate, supports the specific lighting device, and matches the required wired or wireless configuration.

Choose light switch faceplates in colors such as white, light almond, brown, black, or satin nickel to coordinate with nearby walls, trim, cabinetry, and hardware. For a cohesive installation, match the faceplate finish to surrounding fixtures and select the appropriate gang size and profile for the lighting devices and Decora-style outlets.
