Chris Hoffman's reply covers just about everything on this matter - I would only add that if you have no running lights (defined as tail lights and license plate light) when the switch is in the headlight position, (and we know you do when the switch is in the park position) there is definitely a problem internal to the switch. The running light connection is the same for both switch positions, and since it works in one position and not in the other, there must be no connection internally when the switch is supposed to provide it in the headlights "on" position. Very likely, if you carefully disassemble the switch and inspect it, you'll find a burned contact or a distorted slider in there - you're on your own to create a fix and reassemble the switch. The turn signals, cornering lights and brake lights are on completely independent circuits, there is no interconnection or shared component with the parking or running lights, so the fact that they operate normally really has no bearing on this matter.
