A protection mechanism for force-based touch sensitive input panels or displays comprising a “snap dome”, e.g., a semi-rigid pliable dome positioned over each sensor for increased overload protection. The snap dome is unidirectionally-resilient to a known point of collapse. It therefore imparts a predetermined resistance to compression over a known range of travel along the z-axis, but is unyielding along the x- and y-axis. As the touch panel is depressed toward the standoff, the snap dome resists compression until it collapses, allowing the touch panel to encounter the standoff. The standoff then imparts dead-stop overload force protection to the sensors. This allows for the placement of mechanical stops (such as stop screws) with a less exacting tolerance. Moreover, the snap domes introduce no x- or y-axis force losses/increases, and do not cause tilting of the touch panel. The touch force remains perfectly perpendicular and accuracy is preserved.
