Abstract

The present invention is a mobile navigation device comprising a roller which comprises an insulated bushing and a conductive ring, wherein by matching the plurality of protrusions on the inner end surface of said insulated bushing with the plurality of slots on one end of said conductive ring, said conductive ring is plugged inside of said insulated bushing; a support which comprises two braces, wherein each of said braces comprises a cantilever that is plugged into said conductive ring to sustain said conductive ring and said insulated bushing; a plurality of terminals which is plugged into the conductive ring by prestress on the inner surface of said conductive ring, and each said terminal extends out of the conductive ring to connect with default circuit contact; and a body which comprises a plurality of fixture parts on one end surface of said body to fix said support, and a plurality of raised spots on two opposite sides of the other end surface of said body to drive circuit switch. According to present invention, the whole structure is simplified and is capable of five transmission movements of forward, backward, rightward, leftward, and downward.

Claims
