Abstract
The switch comprises a body carrying fixed electric contacts and a movable member rotatably mounted in the body. The body has curved ribs of identical radius which extend around a barrel and define between them a plurality of free spaces containing electrically conductive balls. At least two of the spaces are partly occupied by the fixed contacts. An electrically conductive ring is interposed between the balls and elastically yieldable members carried by the base of the movable element. The conductive ring is put in contact with the fixed contacts through the balls, which constitute moving contacts, and closes the switch electrically when the movable element is rotated relative to the body. The edges of the ribs constitute abutments for the balls.
