OK, so you have a 3-way switch to control the ceiling light in your hallway. Coming from your family room, you flip the switch to turn it on. At your bedroom door, you flip another switch to turn the hall light off. Simple.
You don’t care whether you flip either of those switches up or down, you just flip it to the opposite setting you found it in.
Depending on who installed those switches, you could find that both switches down results in the hall light being ON or OFF. That guy probably didn’t care which way it would be, just like you don’t care.
I care.
I have installed a fair number of such 3-way switches over the years, and I always make sure that if both switches are down, the light is OFF. If one switch is up and the other down, then the light is ON. It’s just a thing for me. Is that OCD or just anal?
