Thanks for the return. The following link shows where I was able to spray cleaner on the switches. http://i38.photobucket.com/albums/e110/Jerry8C/005.jpg

At this level of disassembly, you will notice the switches are mounted on a printed circuit card. And the card has plastic guides on each end. I could not see clearly to the bottom of the card, but I was trying to determine if this card was removable. I tried to pull on the card and it did not move. I did not want to use too much force, since I thought the card might be soldered in at the bottom. What would be your guess?

Anyway, this is where I am at this point. Now to be more specific about the switch action, when I press down to where the switch is suppose to lock in place, I can feel something like a shoulder being locked into place. And, on some switches, this shoulder feels like it might be worn where the locking action does not always take place. Is this about the best I can expect to do?
