摘要
Present invention relates to a roller construction with a sense of feel for a mobile navigation device; more particularly, relates to a construction for a mobile navigation device to produce a sense of feel when rolling the roller. Present invention comprises a conductive ring, a plurality of terminals and a support. The conductive ring is a hollow ring of conductive metal and the outer surface can be covered with insulating material. Each of the terminals comprises a contactor and the terminals are connected with the default circuit. Each of the contactor is plugged into the conductive ring to be electrically connected with it. The support comprises two braces, wherein each comprises a cantilever plugged in from each end of the conductive ring to support it. On rolling the conductive ring, regular interferences are made between the terminals and the conductive ring, or between the conductive ring and the cantilever, to produce a sense of feel.
