The string breaks before you pull the switch down.

Just had a quick look at my (20-year-old) lecture notes,
and protection by out-of-reach can only be applied to
outlets/appliances, not to circuits, such as a light fitting
on a high ceiling, protected by virtue of requiring a ladder
to reach and twenty-foot arms to be able to touch another
conducting part.
