    • Remove the switch cover by jamming a flat head screwdriver into the gap between the outer frame and the switch cover.

    • Some manufacturers, like Busch-Jaeger have an extra frame beneath the switch cover, so you'll have to remove that as well.

    • Remove the frame

    • If you can't remove the frame because there's a wall socket on the same frame, take a look at this guide, on how to remove the cover of a wall outlet.
