Abstract
Capacitive sensor assemblies for electronic devices, and methods of forming capacitive sensor assemblies. The capacitive sensor assembly may include a top component having an intermediate layer formed on the top component, a bottom component positioned opposite the top component, a silicone layer positioned between the top component and the bottom component, and a first electrical trace positioned adjacent the silicone layer.

12. An electronic device, comprising:
-
a housing defining an opening and an internal surface forming a first electrical trace; a transparent layer positioned at least partially within the opening and defining an input surface; an opaque layer positioned on an underside of the transparent layer; a capacitive sensor assembly positioned below the transparent layer and along the internal surface of the housing, the capacitive sensor assembly including a second electrical trace separated from the first electrical trace by a deformable component, wherein the transparent layer is operative to compress the capacitive sensor assembly and move the first electrical trace and the second electrical trace toward one another, thereby triggering a switch event. - View Dependent Claims (13, 14, 15, 16)
