It's a rainy day in Florida so time for a quick $10 mod.
We have a factory installed Dirt Devil central vac. It works great! However, there is one thing that has always troubled us a bit. What turns it on is the lifting of the outlet door when you connect the hose. That's ok until the phone rings, or nature calls, or ?? and you want to shut it off temporarily without unplugging the hose. Easy fix was to install a switch that controls power to the outlet.
Cut a hole for the new switch, used bailing wire to fish the wire (24v 18/2) to the outlet then spliced the wire inline to one of the two wires on the outlet. Tested it, then closed it all up. Total time was under an hour.
