Claim 5:
6. The input device as claimed in claim 5, wherein the optical sensing sub-arrangement comprises:
a light emitter which is disposed at an intermediate level between the plunger element and the at least one mounting panel and which is oriented to emit light along a light path perpendicular to a biasing direction of the biasing element;
a light sensor which is disposed in the light path and which is configured to generate the analog signal based on the amount of light sensed by the light sensor for outputting via the output terminal; and
a light blocking element which is associated with the plunger element in a manner so as to be movable together with the plunger element along a movement direction parallel to the biasing direction and which is extending towards the mounting panel to intersect the light path between the light emitter and the light sensor, wherein the light blocking element comprises a cut-out profile which varies the amount of light passing through the light blocking element as the light blocking element moves transversely across the light path when the plunger element is moved towards the at least one mounting panel.
