1993 940 Fan switch Question

Quick question...The fan switch that presses into the radiator, what temp do they usually activate the fan at? I ask, because it sure seems to wait a long time before it closes and turns the fan on. I know modern cars use electronics to disable the fan above a certain speed. I'm pretty sure this 940 is not that advanced and is a simple on or off. So I'm assuming its pretty high to prevent the fan from running all the time. Air from driving should keep the temp below the activation level and really only activate the fan when sitting still long enough to get the water temp up to the switch temp. Anyone know for sure what that temp should be?

Also if I am wrong on how it should work, let me know.

The push in fan switch is 92?-87? according to this FAE catalog (part #36070).

They list 2 other switches with the same design but both are higher temp. 36080 is 96?-88? and 36290 is 102?-97?.

OK makes since. It's not even turning the fan on at anything below 188 F
