Yeah, that’s a key difference between the dimmers you have and the non-dimming micro-switches I’m using. I would not be surprised if the use of line voltage in the switching circuit is the root of theat last some of the issues. However, I’ve been having issues even after changing over to using the line voltage passed through by the switch, rather than tap in directly from line as the instructions show. Of course, the micro-switch on the SPST switch is still alive… Perhaps it has something to do with the difference between trigger modes. Beats me.
Here are some pictures and drawings since most things have been described in writing.
One circuit also has a four-way switch between the three-ways.
