I deleted the previous post with colors and trip points from memory. Here's info on all but the red switch -

IIRC the red switch has trip points of 95*C and 105*C. The trip points are etched into the wrench flats of the switch.

Jeremy mentioned that he experienced the aux fan kicking in with the coolant temp gauge around 100*C with a red switch. Then he fitted a new fan clutch and the engine didn't run that hot.
