  • Publication number: 20230126341
    Abstract: A portable information handling system touchpad detects button inputs with a downward press at the touch surface that translates to a central button under the touch surface through a frame biased up by a central beam and plural biasing members. Downward presses at the touch surface off center translate towards the center of the frame to provide a central button input that is attributed with right, left and or center button push input values based upon detection of a location at which the downward press touch is sensed by the touch surface.
