Ignition key is hot - temp wise

I had a 73 Dart with lighted bezel. Never got hot.74 DartSport no lite no heat either.None of my Mopars ever had heat in the key.Not column mounted nor dash mounted.So Id have to say..not normal.
I Would be digging into it in a hurry have a look see, before a little heat turns into a lotta heat.
When they went to steering wheel locks, they divorced the key mech. from the switch, so theres almost no way for heat to be in there. The earlier assys had the contacts attached to the back of the switch part. So those could be heated by an electrical problem.Especially a loose connector on the backside.
Lets see what others say...
FYI, it could be anything on the run circuit, not necessarily drawing excessive current, and the sw could be just the weakest link.For instance a high powered stereo pulling through that sw, or the heater, etc. Point is even if you replace the sw.,you need to look to the possibility that something else could be calling the play.
And FWIW, I have an original sw in my 68. Its so worn out that when I take off hard, the key, with nothing more than the trunk key attached, flies out heading for the backseat, leaving the sw in the run position. Then I know those 295s are working! heh-heh.
