Abstract: An electromechanical data input mechanism 200, 700, 750 comprises a first structural entity 210, 710, having a first surface 211 and a conductive coupling area 107 on said first surface, and a second structural entity 220, 720 having a second surface 212 located adjacent to said first surface and separated therefrom by a gap. It further comprises a dome-like member 102 adjacent to said conductive coupling area, and extending from the second surface, an actuator 105 adjacent to the dome-like member. The mechanism is characterized in that within an pressing area elastic properties of the second structural entity are substantially uniform and said first and second structural entities are kept apart from each other solely through the dome-like members, and said first and second structural entities are arranged to move with respect to each other so that under the influence of a force pressing them towards each other, the actuator moves towards the dome-like member.
