I’ve come across something I’ve never seen before and can’t find anything on the internet about. My house has a light switch by the front door that powers my exterior lights. The switch has 3 positions up = on, center = off, down = blinking lights and beeping switch?!
The house has built in the 1950’s and some circuits are non-grounded.
This is a mystery as I can’t find any information about this switch, how it works and what it’s purpose is. I’m going to pull it out of the wall later in a day or so, but wanted to see what I could learn beforehand. Has anyone seen this before?
