Patent ID: 7728815

Claim:
A multi-direction input device, comprising: a direction wheel which has an axle and a first side coupled with a coaxial gear, and one-degree of rotational freedom for rolling forward and rolling backward, and two-degree of freedom for moving leftwards and rightwards, and downward for clicking; a toggle mechanism which is located on a second side of the direction wheel and includes an upper arm and a lower arm that are coupled together on a juncture to form an elbow, the upper arm having one end bracing one end of the axle, the lower arm having other end fixed; and a plurality of electrodes, including: a first electrode, a second electrode and a third electrode that are located on the second side of the direction wheel, the direction wheel being depressible downward so that the elbow pushes the first electrode to connect electrically with the second electrode; the direction wheel being movable to the second side such that the axle drives the first electrode to electrically connect to the third electrode; a fifth electrode, a sixth electrode and a seventh electrode located on the first side of the direction wheel, and a conductive and elastic movable contact located between the fifth electrode and the seventh electrode that has one end electrically connected to the sixth electrode and another end in contact with the coaxial gear constantly, the movable contact being not in contact with the fifth electrode or the seventh electrode in normal conditions, the movable contact being driven by the coaxial gear when the direction wheel rotates to be connected to the fifth electrode or the seventh electrode; and a fourth electrode and an eighth electrode located on the first side of the direction wheel, the axle driving the fourth electrode to electrically connect to the eighth electrode when the direction wheel is moved toward the first side.
