Custom made high quality silicone single buttons/prototype keypads

Prototype keypads can help establish the molded control geometry within a developing electronic product. A custom silicone single button allows its face, flexible support, and base to be evaluated against the intended housing and mechanism. Color and printed or molded identification can be considered once the operating relationship is understood.

Evaluate the part in the assembly conditions it is meant to reproduce. A button tested outside its housing cannot show how perimeter clamping or side clearance affects travel. Check centered presses, angled touches, release after a held action, and any interference near the opening.

Use those observations to define the final dimensions and support arrangement. The visible height should be related to the internal mechanism position so that the button remains at rest until intentionally pressed. Keep contacting regions clean during fitting and record the orientation through the development process. When a revised component is installed, check the complete interaction again if its geometry or surrounding support has changed, rather than assuming that a similar appearance produces the same assembled behavior.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Check centered presses, angled touches, release after a held action, and any interference near the opening.

Custom dimensions

The visible height should be related to the internal mechanism position so that the button remains at rest until intentionally pressed.

Fit & assembly

When a revised component is installed, check the complete interaction again if its geometry or surrounding support has changed, rather than assuming that a similar appearance produces the same assembled behavior.

Use & inspection

Keep contacting regions clean during fitting and record the orientation through the development process.
