antique vintage Levolier pull chain light switches patented electrical hardware brass & bakelite

Lot of two untested vintage Levolier pull chain switches - one metal, one brown bakelite. These have a very hard pull, I didn't give them any more than a quick tug so as not to force them unduly. These might work much better when they're in place, or maybe they need cleaning or repair to get them to run smoothly. I just don't know.
