Capacitive Jog Dial

Abstract

The present invention discloses a non-conductive conductive jog dial. The non-conductive conductive jog dial according to the present invention receives rotation and pressing operations and is provided in the shape of a disc made of a conductive material, with a rotation axis protruding from the lower center, and a hand contact direction sensing projection having a ring shape formed on the outer side concentrically with the rotation axis, and a contact projection protruding at the same height as the hand contact direction sensing projection on one side of the outer edge of the lower surface of the body; and a sensing sensor disposed opposite to the lower side of the conductive lever, having a sensing pattern portion formed on the upper surface in which a plurality of contact channels that conduct electricity by contact with the contact projection are partitioned, and a touch chip circuitously connected to the sensing pattern portion through a via hole on the lower surface. The present invention, with this configuration, is equipped with a capacitive change sensor to prevent unintentional operation by the user, thereby increasing the reliability of operation and eliminating durability limitations caused by frequent operation, which ensures an extended product lifespan. This not only enhances the marketability of electronic devices employing the invention but also has the useful effect of improving consumer satisfaction. In particular, since no elements constituting a physical button are used, the occurrence of mechanical failure can be minimized. Furthermore, compared to a physical switch structure, the structure is simplified, which has the advantage of increasing the freedom of design for various products.
