In a medium bowl, combine the ground beef, garlic powder, onion powder, salt, and pepper. Mix until the ingredients are evenly distributed.
Form the beef into four equal-sized patties.
Heat a large skillet over medium-high heat. Add the patties and cook for 3-4 minutes on each side, or until cooked through.
Meanwhile, heat a separate skillet over medium-high heat. Add the butter and onion slices. Cook for 4-5 minutes, stirring occasionally, until the onions are caramelized.
Toast the buns in a toaster or in the skillet for 1-2 minutes. Place the cooked patties on the bottom buns, top with a slice of Swiss cheese, and top with the caramelized onions.
Place the remaining buns on top and serve.
