Hi Xathros,
That is an interesting hypothesis. I just went and checked my ToggleLinc (it is not mounted in the wall, so I was able to remove the side panel of the switch box), and it did not feel warm to the touch. I appreciate your helpful suggestions.
Hey Brian H,
I am new at this forum and just catching on to some of the nuances of posting. I did not notice that the original problem was for a dimmable switch, otherwise I would have been clearer in my posting. From now on, I will do as you suggest and start a new topic if there is any chance that my posting is a unique issue. I appreciate your assistance and suggestions.
