  • Switch
    Patent number: 12002633
    Abstract: A switch according to one or more embodiments may include a movable unit movable in response to an operation. A drive unit is drivable in response to movement of the movable unit. The switch may include an operation-linked unit movable in response to the movement of the movable unit and an operation follower unit spaced from the operation-linked unit to move in response to movement of the operation-linked unit with a magnetic force between the operation follower unit and the operation-linked unit. At least one of the operation-linked unit or the operation follower unit is magnetic. The drive unit is drivable in response to movement of the operation follower unit. The operation follower unit accommodated in a chamber is spaced from the operation-linked unit.

  • Electrical connector
    Patent number: 6817898
    Abstract: In a non-symmetric pin assignment where a differential pair of contacts and a ground contact are arranged in that order, a conductive finger portion electrically connected to the ground contact is also arranged in the proximity of one of the differential pair of contacts which is positioned farther from the ground contact, so that an imbalance on impedance arising from the non-symmetric pin assignment is compensated. In the case where the differential pair of contacts and the ground contact are arranged in the same horizontal line, the conductive finger portion is located above or below the contact farther from the ground contact.
