I was thinking I maybe should have put this A to Z dust switch post in this area on Bot modifications instead of in "Show & Tell."
It's a mechanical switch using a lever and a spring to change dust collection between Zs. It's activated when the AUX Z is parked.
The write up with details is in this thread:

Here's a link to a short video on both the boots and the switch.

Here's a photo with the parts labeled. [Could someone tell me how I make it display as a clickable thumbnail?}
