Zusammenfassung:A touch sensitive surface (401) for an electronic device (200) includes a capacitive touchpad (409). A grille (413) of non-conductive material (515) is disposed along at least a portion of the touch sensitive surface. A predefined threshold of a normal force component (804) applied by a user's finger or other conductive object overcomes the grille (413) to allow the finger or other conductive object to interact with the capacitive touchpad. The touch sensitive surface reduces false touch activation occurrences and can simulate the tactility of a mechanical switch.
