Sample Implementation: 11 mm Green Start Button on Rubber
Membrane
One construction that can be used to implement the Green Start button is to place the keycap
and dome on a rubber actuation membrane. The rubber membrane must include an orientation
feature to align with the orientation feature on the underside of the keycap.
Alignment of the orientation features on the keycap and rubber membrane ensures that the
Green Start button subassembly is oriented to the device axis correctly. The following drawing
illustrates this type of construction.
