Thank you every one for your help and suggestions what I found was after a closer look and investigation that the blades/contacts were burnt or somewhat arked together and did not open fully resulting in voltage leaking through from power company transformer, now my search is for a replacement.
It is not unusual to find a 50%, or higher, failure rate for these switches if they have not been operated at least once every 3 years.
If it is just a case of stickiness, then a good service shop can properly maintain it for you. FWIW, if the service techs show up with just 'WD-40' and some rages, do not let them in the door.
If parts need to be replaced, there are lots of rebuilt units available. There are even options for replacement, in place, using breakers instead of fuses (which can be helpful in some arc flash mitigation when fault currents are low)
