Set of luminous display hands for a portable object such as a watch or a measuring instrument

摘要

A set of luminous display hands is for a portable object including a frame housing an electrical energy supply source that includes a first and a second terminal. The set includes at least first and second luminous display hands made of an electrically non-conductive material. A drive arbor of the second display hand is arranged concentrically inside a drive arbor of the first display hand. Each of the first and second display hands carries a first, respectively a second light source which emits light. The first and second light sources each include a first and a second pole. Depending on whether the light sources are mounted in parallel or in series, the first pole or the second pole of the second light source is connected to the first pole of the first light source by contact between the first and second hands.
