As the title says: I am owned by this good sized ranch home. The raw basement is all for RR use with an somewhat extensive around the wall layout with track work nearing completion. At this late stage of life I am more concerned with getting the rails done instead of finishing the basement. Just making it practical. There are five lighting circuits. Four of which the ADD owner occasionally leaves on. (Guilt, guilt, guilt.)
Two of the areas are well defined where a motion activated switch can be wall positioned. However there is another large area with two circuits where there is no favorable wall position to mount either of the motion activated switches.
While leaning against the concrete filled pole trying to mentally envision a switch location this cold hard force on my back begged a look-see. The location was fabulous, the mounting was "Like how??". No thought to boxing the pole, just mount the stupid switches. After turning around, measuring the pole's diameter, checking my hole saw assortment and pulling out some 3/4" plywood scrap I fashioned the below example.
I bored a hole in the top plate, cut it in half allowing for the flex conduit to enter the top, fashioned the sides with holes to mount the Eastern facing and the Western facing motion activated switches, glued and clamped the top plate in place with wood glue for the slice and premium poly urethane construction adhesive for the contact with the pole then splashed some poly coat on the wood--wallaa, my motion activated switches had a perfect location. The pole was sanded to bare metal for gluing on the conduit drop and box. It has seen several months of use so I know that this was a practical endeavor.
Go and copy it yourself and make yours "purty":
Please do one better than mine, add a duplex outlet.
