Light Switch Cover

thingiverse

I've designed three versions of a light switch cover so far to keep my two-year-old from messing with toggle/decora/rocker type switches. My design is low-profile and allows for easy addition to existing switches by simply removing the plate screws, then replacing them while placing the cover over the switch in place. We store the key on top of the trim right next to the door beside the switch so our son can't reach it easily. You don't have to use a key; you can use any other thin object you prefer to turn the switch on and off.
