Thanks.
Interesting, they went back to a single dimple contact rather than the double dimple. Plating appears the same. I've seen them change these contacts over and over again. I wonder why they can't settle on a design. I take it you don't have a set of calipers to measure the PCB thickness. If you lift off the switch contact holder from the brass hex shaft, is there a shim under it?
PCB has some changes. New clamp design. I wonder why they changed it and it it improved its electrical robustness. With it being Dave's meter, I am surprised he doesn't show off the changes and explain the reasons for them. Maybe he did and I wasn't paying attention.

Just an FYI, I had bought two of these to review. Showing the board of the unit that was damaged during the grill starter. Notice the changes.
