Looking for a good high quality 2 stage temp switch for my electric fan setup. Looking for recommendations from those that have tried, returned, failed, etc. I don't want to shop blindly so I'm hoping I can see what people like the most. Needs to be something that can turn on 2 different fan speeds. Something like a 185* and 200* or something ......I dunno. Or should I just get 2 different temp switches??? Also, in the head preferably right ?? thanks.
