Hello There
I have a ceiling fan 3 speed 4 wire that someone else worked on at the church I attend.
My question is gray wire #1 Purple #3 Black ? Brown? also the Purple wire is smaller
Than the other 3 and it goes to the reverse switch.
I would be thankful for any help.
Thank You

Their was info on many fan switches, your color included on this site, can't find now. I have provided answer in one of my post, hard to find in over 3000.
Hope info will be back, or someone will tell where to find on this site.

Black - L, Grey - 1, Brown - 2, Purple - 3.
