The most frequently used push button switches (for me they are BAND+, BAND-, MENU, MODE, XFIL, A/B, A=B) do go bad after a while. I own a pair of K2/100's and I've had to replace all of the switches I've already mentioned on each rig.

I'm friends with a couple of other local hams and they have had to replace some their frequently used switches on their K2's as well. So its not really that rare of an occurrence as they do start to malfunction after a while.

Steve,

That certainly sounds like you have one of those rare occurrences - a
bad switch.  It certainly can happen - actually most any part can fail
at times, but a bad switch is quite low on my list of usual suspects.
