The switches that mount on the manifold usually go through into the coolant galley. Therefore they are monitoring the temperature of the coolant around the engine and hence engine temperature. Since it is the engine temperature that needs to be regulated they make sense. They are usually a thermostatic switch and aren't the same as a conventional coolant sensor.
