Simple switch

Here’s a simple way to turn something on just by opening the door – good for halloween projects.

  1. Simple? If cutting the drywall & door framing, installing an electrical box and wiring (not to mention installing a switch that’s not meant to be operated by contact with a door) are “simple,” I’d hate to see what Phil thinks is “complicated” !!!

  2. This IS actually pretty simple…as long as you have done some level of framing/drywall. I built a server room in garage with zero experience in either and it actually ended up being A LOT simpler (thought not necessarily easier or less work) than I expected. I rigged up a lever actuated video game arcade style switch to turn on the lights in the server room when I opened the door. It’s kind of gangly and hacked looking. This looks quite a bit cleaner and more stable. Definitely going to give it a try.

    My question is, what the heck kind of room/door is that? Is that noise insulation padding on the door? I’m intrigued!

  3. Reminds me a lot of the one-way switches they have on commercial deep freezers and walk-ins in restaurants and supermarkets. Those switches are a little more complex, though…they use a rocker mechanism to help keep the top of the door secured as well, but same usage.

  4. I have a light in my server closet that I wanted to turn on only when the door was open. They sell a in-door-frame switch at Home Depot. You cut out a area of the door frame (Hinge side) Installed in only 30 minutes, and cost less then $10.
