I originally liked the idea of zen switch. To me, it was sort of like, "you have to DO this in order to make everything come together right, not just mechanically go through the motions."
But, I think many people don't get it, and a few people get hung up on the "new-agey" terminology.
Since swing switch focuses on what you are DOING, I think it is a great terminology.
In the same vein, I like "focal points" better than "stroke thoughts" because I think focusing is more important in swimming than thinking. An alternative would be "stroke focuses" but that is hard to say and confusing. Focal points does come off sounding pretty generic, but I think it works.
Something that could be considered is if there are important focal points, to give those actual names as well. That would raise their importance and not just be "another focal point."
