You don't want it on all the time as it will drain battery over time. Its not just a gauge, it usually has a light also.
Often they are on a momentary switch but it is hard to pump gas and look at the gauge by yourself. Mine is on an on/off switch and it freaks passengers out when we're 60 miles out and the gauge says Empty!

You can connect them to the Ignition Key switched power (purple?).

You say "grounded thru a switch". that would not be right if true.
