A switch is open or closed and actuates a relay

I re-read your post and wanted to elaborate.
The fact that you have dim lights on the dash make me think it's not your ignition switch. The switch controls a relay(s) which in turn powers on and off to different relay(s) depending on the position. This is to say that a switch should either work or not. If a relay is opening to light the dash lights dimmly, then the path from the battery to the lights is complete. A switch cannot partially function to in turn cause a relay to partically funtion.
Basing this as a resistance issue - some how, somewhere the full power of the battery cannot do it's job and light the dash lights fully or allow electrical functions in the car.
I'm not sure how much digging you want to do, but a schematic and a DMM will help.
There are other possibilities for the problem, but I would rule them out and focus on the issues that have affected other Saabs.
Hope this helps.
