Claim:
1. A dome-shaped element disposable in a keyboard of an electronic device and comprising: a concave surface originating at a center and terminating at a periphery; the concave surface comprising an annular array of elastic elements extending from the center to the periphery, each of the elastic elements comprising a first substantially linear portion with a first slope proximate to the center and a second substantially linear portion with a second slope proximate to the periphery, wherein at least one of the first portions of the elastic elements is tapered toward the center; and the concave surface being deflectable between an un-deflected position and a deflected position and configured to affect an operation of the electronic device in the deflected position, wherein the first slope is the slope of a line parallel to the first portion, and wherein the second slope is the slope of a line parallel to the second portion, and wherein the angle of the first slope relative to a surface of a substrate on which the dome-shaped element is disposed is less than the angle of the second slope relative to the surface of the substrate.
