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?


It sounds like an emergency light blinker, to let 911 responders or visitors know which house to go to. Found on google this one, https://www.amazon.com/ge-7250269-emergency-flashing-activator/dp/b002w552ng. The beeping I think to let you know the lights are on blinking.

  • @Harper-ReinstateMonica Got lucky with google, only hit with blinking, many for flickering.
