Every once in a while, I run across this envelope filled with old controller switchplates. If you are missing a switchplate in your cabinet and happen to see it here, let me know!
Not really 'on topic' (as none have the slightest to do with signal stuff) but anyways...here's what I did with a handful of orphaned nameplates from various semi-interesting "old things"...
(...just a scrap of thin MDF cut to fit an antique oak mirror frame (probably?) rescued from an attic, with some felt fabric lightly glued to it before arranging/attaching the plates with tiny brass screws...)
if 'ya don't find any takers for all those switchplates, I'd volunteer to take 'em off your hands and go looking for another old frame needing something new to fill it...?
