Hi,
I noticed that we haven't heard from you for a couple of days. Have you made any progress? Do you have any additional questions?
As far as the switch, the guys are correct. There is a button that releases the knob and stem. Simply pull straight out on the knob while you have the release button pressed.
Let me know if you get it.
Take care,
Joe
