STRESS-LIMITING DEVICE FOR FORCED-BASED INPUT PANELS

摘要

A system for preventing damage caused by the application of excessive force to a force-based input device having an input panel supported by a plurality of deflecting beam segments, in which the excessive force could cause permanent plastic deformation in the beam segments. The system includes a stress-limiting device operable about the deflecting beam segments to control the motion of the beam segments to within a pre-determined range.
