Pulled out the old 3 position switch(lost it) but can only find a 4 position switch. I need to know what color wire is for what so I can wire it spade by spade

Hi,
As far as I can tell , you are speaking of in compatible switches that do not fit in the same hole, use different keys and are manufactured by different companies.
I believe you want the AM119111 made by Indak.
The other is a GY00191 made by Delta.
Peace,
Clarke
