A self-centering device for assuring that two plates that are rotatable with respect to one another will automatically align in one of two-stable positions. The device includes an O-ring entrained about two spaced posts located on the upper face of a bottom one of the plates and a roller depending from the bottom face of the upper one of the plates into a circumscribed space defined by the O-ring. When an external rotatable force is applied to the upper plate, an elastic force is applied to the roller such that when the external force is removed, the roller will move into one of the two stable positions.
