And we find that the total depth of each grass hopper knee is 0.140 inch. With the contact point centered in the raised portion.
The contact point (center of knee) for the front pair is 0.170 inch in from the connector edge and for the rear pair is 0.310 inch in from the connector edge.
The knees are 0.030 inch high (in the 0.040 inch high slot).
Since the "inside, front" (shown right of center in the sketch) is GND, we will also want to stagger the engagement points on the tab so that GND gets connected before the CMOS Tx and Rx contacts.
The "outside, front" (shown at the right side of the sketch) is the light control sense lead, we will not be bringing that out on our connector tab.

And keep in mind that the sketch is of the "cover" part of the connector, shown "upside down" (board side up).
(Which will be its orientation when using the Kindle - since the Kindle is upside down for the photographs.)
