Abstract
Input devices having a thin profile and good comfort and feel are disclosed. In embodiments, an input device includes a sensor layer configured to effectuate a key press upon application of an activation force, and a collapsible layer coupled to the sensor layer. The collapsible layer may be configured to collapse in response to a collapsing force that is substantially equal to the activation force. When the collapsible layer collapses, the sensor layer may simultaneously effectuate the key press in response to application of the collapsing force.
