Reminds me of a self-employed (and trained) DJ... he had his own light control box, basically a wooden box with a pile of regular light switches and Schuko receptacles. At least they had covers.
the feed however... he had a spare, unswitched receptacle on the side and used it to backfeed the entire box using a cord with two plugs! (and yes, I mean two male cord caps...)
I just found it on my photobucket account.
The plug on the left hand side runs the entire thing.
