Small 1969 condo. All outlets grounded except for one in the bedroom connected to the wall switch (the whole receptacle…not just half). No ceiling light. As it’s a three prong I feel it should be grounded…BUT, because it could only be practically used for floor or bedside lamps the chances of any three-prong device being plugged in seem very remote.
I'm recommending the outlet be changed to a two hole receptacle or to a GFCI (marked no-ground). Running a ground wire is likely impractical. But I'm wondering if there is any exception for switched receptacles?

If the conduit was of metal, like rigid metal conduit or electrical metallic tubing (thinwall) they would be recognized as an equipment grounding conductor, and if they were properly secured and tight at all joints and connections from the source to that outlet and switch box, the EGC would be there, and replacing the two wire receptacle with a 3 wire grounded type of device would do the job.
Did you mean THW?
