The problem I see with must bad golfers is that they try to "pull" the club through with their left arm, which leads to all sorts of malfunctions.'
What you are describing is a hitter's action. If you want to be a hitter, that is fine.
However, a switter is a golfer who combines swinging actions and hitting actions.
A swinger uncocks the left wrist by the release of PA#2 - which is a passive action and the force involved is a CF. The only active force that a pivot-driven swinger applies in his 4:2:3 release action sequence is due to the fact that the pivot drives the left arm through PP#4. When the pivot subsides, PA#4 releases and the left arm catapults forwards away from the torso. The moving left arm pulls the clubshaft via the left hand's grip at PP#2. That's the only force that a swinger applies actively - a pulling force at PP#2. The club eventually releases passively due to a CF action, and then PA#3 eventually releases passively.
A switter, by definition, must be applying an additional push force at some time point during the downswing. If you are a switter, then I would like to know when/how that push-force is applied.
