Abstract
A universal adaptor plug is disclosed as an encased arrangement of elements, which includes a single rotatable knob for attachment to and for rotation of a cam axis for mounting at least three cam elements. The front face of the casing defines openings through which project multiple sets of plug pins movable by the cams and cam followers. Each set of plug pins is attached to a base which causes retracting of the plug pins by the base's attachment to retracting springs. The continuous unidirectional turning of the knob, in turn, projects and enables retraction of a set of plug pins for a certain country or group of countries.
