I recently was redoing the cooling fan and electrical system supporting it. After looking at the switch specifications in the back of the catalogs at NAPA, I was unable to find one smaller than what I am currently using that had the temp setting I wanted. I an currently using a switch sourced from VW (Bosch), I think it fits a VW Rabbit or Golf. I was attempting to find a smaller switch (currently 22 mm thread) with two terminals but everything listed had a higher closing or opening tempratures than what I was comfortable with. That agrees with the fact that most of the later model cars that actually have electric fans operate at higher tempratures, many at or above 200 degrees, leaving a very narrow margin for overheating and coolant loss therefore 15-17 lb radiator caps, and sealed cooling systems.
