1998 Nissan Sentra–dead key–ignition switch prob

Hi all,
I have a manual transmission 1998 Nissan Sentra. I first knew i had a problem a couple weeks ago. I got in the car to go to work in the morning. I turned the key and all electronic things came on, but no cranking. there was no click or anything, nothing was being sent to the starter. I turned the key back and forth several times and it started.

Well a couple weeks have passed with no issue. I went to go get lunch yesterday and got back in my car and turn the key and absolutely nothing. No dash lights, no electronics. Another interesting clue–the only electronic light that comes on is the airbag light and it is very faint and it kind of flickers.

Battery is fine. I am thinking it is the ignition switch. The part is only about $27 at AutoZone. Does this sound like the ignition switch? Any advice would be greatly appreciated!!

thanks,
Kevin
