Excuse me wading in, but we're at Post 21 now and I see no indication that any "qualified" person has looked at his suspected problem, or that the maintenance organisation/mechanic has been consulted about it. With the greatest respect to the pilots and Instructors on here, and on-site, flying is your area of expertise, fixing things is ours. <br /><br />I'm 3 or 4 years retired now but, back in the day, there were a number of Service Bulletins extant on the subject of ignition switches. They go wrong; sometimes seriously. A mechanic is best placed to give advice, discuss possible failure modes and to gain better access to the switch, its wiring, and adjacent components to perform a proper inspection.
Edit; Appreciate and acknowledge Uplinker's post below. I should also add that, if the OP is a student, I appreciate that the presence of an authority-gradient may not make this as easy as "just do this, then do that".
