A motion control device for controlling the movement of an operational member about a first axis and about a second axis includes a spindle having a socket and a control arm wherein the socket defines a first axis opening. The device includes a cylindrical pivot member inserted into the first axis opening concentric with the first axis. The pivot member defines a second axis opening and the device includes a cylindrical pivot pin inserted into the second axis opening concentric with the second axis. The spindle is designed to pivot in a first direction about the first axis and in a second direction about the second axis wherein the first and second axes are orthogonal to each other. In one embodiment, a hexagonal drag spring is inserted between the pivot member and spindle to influence the frictional drag for one of the two directions of movement. |
