The wall plate for three switches mounted in a 3-gang switch box is called what?

The wall plate for three switches mounted in a 3-gang switch box is termed a three-gang, 3-hole switch plate because it is specifically designed to fit over a box that accommodates three switches. The designation "three-gang" refers to the number of switch openings in the plate, indicating that it is meant for a configuration that allows three different switches to be installed side by side.

This specificity is important in residential electrical installations, as using the correct wall plate ensures that the switches are properly covered and that there are no gaps that could potentially expose live wires or create aesthetic issues. The "3-hole" in the name reflects the fact that there are three designated openings for the switches to operate through the wall plate, which is essential for proper functionality.

Other options refer to different configurations: a single-gang plate is meant for one switch, a two-gang plate for two switches, and a four-gang plate for four switches, making them unsuitable for a situation where three switches are installed.
