Here's an old light switch that's in the basement of a house across the street from us. It works like any light switch. Click it one way and it’s dark. Click it the other way and the light's on.
Notice anything odd about it?
(Does anyone know why it would be this way? It's cast metal so it's seems like an unlikely mistake.)
Here's this week's new video!
These Aqara products solved my problems with taping over my switches!
My current home in Melbourne is my first house in Australia where the lightswitches make sense. The button closest to the kitchen turns the kitchen light on, and not an overhead light in the hallway. The switch closest to the door turns the outside light on, and not a back patio somewhere. Only recently realised how much I missed that sense of sanity in my life in the last 13 years 
Here's a plank of wood with three old light switches on it, a battery pack and a few LEDs.
Who would want such a thing ? Our ~18 month old grandson. He's fascinated with switching the lights on and off so I made this as a Christmas present so that he could safely flick switches as much as he likes and watch the lights go on and off.
It got dropped and one of the light switch covers broke (bakelite-like plastics aren't great with impacts) so I just repaired it with a new (old) switch cover.
