An information handling system keyboard extends plural feet from a bottom surface to reduce contaminants at the bottom surface that might scratch a touchscreen display and retracts the plural feet when resting on the touchscreen display to place a non-scratch and contaminant free surface against the touchscreen display. In one embodiment, the plural feet automatically retract when in proximity to a display surface, such as in response to a magnetic sensor integrated in the keyboard that senses a magnet integrated in the display or in response to a command from an information handling system having an integrated display on which the keyboard rests. In one embodiment, the keyboard integrates accelerometers to automatically extend the plural feet during accelerations and retract the plural feet when the keyboard rests on a display after accelerations.
