Are you sure you want to do that?


Covers for outdoor electrical outlets adapted to gently lock-out some light switches in a market research facility observation room. Behind a two-way mirror, the room must be kept darkened, and so the use-with-caution light switches are kept separated from the use-at-will light switches. The cover hardware, adapted from its intended use, doesn’t prevent operation of the light switches, but you have to think more deliberately before flicking them. This is a reasonable example of a forcing function.
