Hitler did have a plan to invade Switzerland. Operation Tannenbaum
But Hitler (or his advisers) was not stupid. Attacking a neutral state would remove all doubts for any other country that was not invaded yet. That's only thing I would like to add to those in the link you provided, which are

• Resistance is guaranteed
• Geographic advantage of the Alps for defense
• Fear of internal conflict within Germany
• Fear of transport lines between Germany and Italy being destroyed
  
• Financial considerations
