PWR_FLAG

 

开云体育

I have attached PWR_FLAG labels to my battery input terminals, but I still get a 'not driven' violation on the positive rail after the on-off switch, which is shown in the ON position. Is this normal, or have I got a hidden error in the schematic?

Hard to visualize what you are saying but the pin has to be defined as power or passive I think.

Kicad doesn't know that switches have an "on" and and "off", so you have
to place the power flag downstream of the switch.

Place one after the switch as well. You could also just ignore the warning.
