  • Patent number: 8626252
    Abstract: An input unit for an electronic device comprising a body, a first switch adjacent a first location of the body, a second switch adjacent a second location of the body, and a third switch adjacent a third location of the body. When the body moves in a first direction to a first position, the third switch generates a signal to activate a first operational mode and the first and second switches generate signals to perform first and second functions when the body moves in a second direction different from the first direction. When the body moves in the first direction to a second position, the third switch generates a signal to activate a second operational mode and the first and second switches generate signals to perform third and fourth functions when the body moves in the second direction.
