Ruber diaphragms are widely used as elements in the mechanisms of desktop keyboard swiches. But loading and unloading behavior of a rubber diaphragm exhibits high non-linearity due to geometric and material effects. In this study, the behavior is acculately analyzed by the finite element method, and the design system is developed using a sensitivity coefficient which is defined as a change of the value of a property parameter against a unit change of the value of a design parameter and the finite element method. By several results of numerical experiments, it is confirmed that this design system is effective to design keyboard rubber diaphragms.
