iPhone: Handset Speaker Stopped Working

After using my Iphone with the iPhone earbuds this morning, I took out the ear buds and found that the handset speaker/ringer (as opposed to the speakerphone) stopped working.

After powering the phone off and on a couple of times, as part of trouble shooting I found:
--speakerphone function worked
--ear buds worked
--bluetooth worked.

I tried the Apple iPhone support site and did two of the non-destructive resets without success. Just about the time I was ready to trek to an Apple store to have them fool around with it, I plugged in and unplugged the ear buds a couple of times and now the handset speaker/ringer works again as desired.

Is there some sort of mechanical switch that is tripped when the plug for the ear buds is inserted that stuck in the wrong position?
