I find the 3 position switch (indicator type) to be better. There is "sticktion" with the gauges and allowing the needle to drop for a second or two seems to produce a more accurate reading.

 

The official terminology is hysteresis - this is the tendency of the reading to lag behind the measurement and in accurate gauge systems is measured itself.... The way to eliminate hysteresis in classical dial gauges is just to knock the gauge gently a few times.. I guess most people will have seen this with their parents / grandparents tapping dial type barometers 😬

Thanks - Hysteresis - I'll try and remember that. At least you knew what I meant. 😬

 

Hehe - you were not wrong with the stiction...! Hysteresis is a combination of friction & stiction in the mechanical system - actually thinking about it the gauge is electro-mechanical so there will be some magnetic hysteresis too, in the core of the coil ;-)
