I had a similar experience with my first SO2R operation at W4AN's (then 
KM9P) mountaintop station during SSB SS. About 3 am, the switch let out a 
loud "ping" when I switched it. After that, there were no more detents -- 
I had worn the detent spring off the back of the switch!

course, he has spend many, many hours of non-contest time listening to 
two radios, one in each ear. If you practice long enough, you can get 
used to hearing different stuff in each ear, and train your head to 
separate them. Then you won't need to switch nearly as often.
