The wall plate for a three-gang switch assembly (three switches) is called which plate?

• A. Three-gang, three hole switch
• B. Two-gang, two hole plate
• C. Three-gang, four hole plate
• D. Single-gang plate

Answer: (A)

Wall plate terminology uses two ideas: how many switches (gang) and how many openings (holes) it has. For three switches, you need a three-gang plate with three holes. That combination exactly provides one opening per switch, ensuring each switch lines up with its own opening on the plate. The other options don’t fit: a two-gang two-hole plate only covers two switches, a three-gang four-hole plate has an extra opening that isn’t needed for three switches, and a single-gang plate is only for one switch.
