I am NO expert, but here is my understanding of it. Hitters use the right arm (right handed) to push the handle of the club down thru impact. Swingers use the right shoulder to almost 'throw' the club down from the top of swing. The physical exerction of the right arm straightening is hitting. Everything else is swinging. Most of us who are just learning this stuff probably have a combination of both in our swings.
