Patent ID: 7446446

Claim:
A rotary electronic component comprising: a case having a fixed resilient contact in its concavity with an open top; a rotor rotatably disposed inside the concavity, a movable contact being fixed to the rotor, the movable contact making contact with the fixed resilient contact; a lower magnet fixed to the rotor on a face which is opposite a face where the movable contact is fixed; a sheet with a sliding part on its top and bottom faces, the sheet being secured to the case so as to seal a contact section, including the fixed resilient contact and the movable contact, inside the concavity; a rotatable operating member disposed on the sheet, the operating member opposing the rotor; and an upper magnet fixed to the operating member on a face contacting the sheet; wherein the contact section activates through: a co-rotation of the operating member and the rotor in an attached state, the operating member and the rotor being disposed at opposing positions with the sheet in between and attracted to each other by an attractive force between the upper magnet and the lower magnet, and transmission of a rotation of the operating member to the rotor while both the operating member and the rotor slide and rotate against the sheet due to an effect of each of the sliding parts on the sheet.
