Abstract
A finger-operated module is incorporated for use with an input device. The finger-operated module has a base having a plurality of walls coupled to each other to define an interior space, a wheel fitted inside interior space and extending through the housing for manipulation by a user, and a resilient element positioned between the wheel and the base. The wheel can be coupled to the base for vertical reciprocating movement inside the interior space when the base is stationary. The resilient element can also be positioned along an imaginary center line that extends through the center of the resilient element and the center of the wheel.
