Ray, It is unusual that you have had multiple pushbutton failures. I repair a lot of KX1s and have never seen a pushbutton failure on my bench. I would think if the switches were not reliable, I would have seen at least one failure. Is it possible that you did not mount the switch body tight against the board? I could believe that a mechanical failure could occur due to flexing of the leads if the switch were supported by its leads rather than the board.
