As a matter of fact, a great and easy upgrade is to replace an old single-pole toggle light switch with one of the newer rocker switch styles such as Decora by Leviton.
Three Sizes for Wall Cover Plates
These three sizes go from smallest to largest:
- Preferred (also Midsize or Midway)
- Oversized (also Jumbo).
Typically, the "Standard" size is used for new construction where construction tolerances are tighter. In situations where drywall workmanship is sloppier creating a large gap between the electrical box and the drywall or in cases where removal of an old cover plate leaves an old paint line, then use of the "Preferred" or even the "Oversized" cover plates work well.
The Standard size plate is nominally 2.75 inches 4.5 inches, the Preferred size plate is nominally 3.13 inches by 4.88 inches and the Oversized plate is nominally 3.5 inches by 5.25 inches.
Use of a larger wall cover plate can save time and effort in non-standard applications where you would otherwise have to patch, sand and/or repaint the wall around an outlet or switch to use a Standard wall plate.
Different Cover Plate Options
Cover plates in these sizes are available in the rectangular shape used for GFCI's and paddle/rocker switches and are also available in traditional toggle style wall switch and rounded outlet cover plate configurations. They are also available in white, almond, and other colors.
