ABSTRACT:
An illuminated electric part includes a manipulating shaft which is rotatable and is stable at least at two points. The manipulating shaft is light-transmissive and includes a pictograph portion which is illuminated at a top portion thereof. The illuminated electric part includes a light emitting element which is arranged at a side of the manipulating shaft. The manipulating shaft includes side faces which constitute light incident faces in directions orthogonal to an optical path from the light emitting element at respective stable points and, at the same time, includes a conical light reflecting face having a downwardly extending top at a side opposite to the incident faces.
