High quality rubber silicone flexible prototype membrane tactile

A flexible prototype membrane provides a development part for assessing the physical response of an input assembly. Tactile behavior should be evaluated with the intended housing, support and contact arrangement, since the loose membrane cannot show every effect of the completed stack.

Customize the silicone or rubber geometry around the key locations and available movement. Compare prototypes using a consistent assembly condition so a change in fastening or support does not obscure the effect of a revised profile. Keep the version of each sample identified during evaluation.

Press the intended operating areas and check return, neighboring movement and contact with the bezel. Include representative input sequences rather than judging the prototype only from one centered press. Electrical response should be assessed with the chosen switching system where applicable. Before production, evaluate any final surface or marking changes in the same assembly. Avoid making unrecorded local cuts or additions to the prototype, because those changes can make the sample behave differently from the molded design being reviewed.

Material options

Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Silicone: 20–80 Shore A. Press the intended operating areas and check return, neighboring movement and contact with the bezel.

Custom dimensions

Compare prototypes using a consistent assembly condition so a change in fastening or support does not obscure the effect of a revised profile.

Fit & assembly

Tactile behavior should be evaluated with the intended housing, support and contact arrangement, since the loose membrane cannot show every effect of the completed stack.
