This table lamp has the kind of on/off switch where it's a straight piece that you push "through" the socket to turn on, and push back to turn off (instead of the usual kind you "twist" on and off).
Anywyay, when I push it throuh to turn it off, I end up touching the outside of the socket (metal). Sometimes this is extremely hot, to the point of being uncomforable to touch it.
However, this is intermittent. One day it may be like that and the next it's not hot. This has been going on a long time.
Any ideas on what would cause this?
