Claim:
1. An input device, comprising: a sensor layer to effectuate a key press upon application of an activation force; and a collapsible layer coupled to the sensor layer, the collapsible layer to collapse in response to receiving a collapsing force that is substantially equal to the activation force, such that both the collapsible layer collapses and the sensor layer effectuates the key press in response to the application of the collapsing force, wherein the collapsible layer includes a plurality of vertical columns comprised of continuous fibers knitted into a three-dimensional spacer fabric, wherein the vertical columns resist collapse under application of force less than the collapsing force and that collapse upon themselves under application of force equal to or greater than the collapsing force, and wherein the applied force is greater than zero.
