Product Overview

Silicone keypads can combine several push buttons in a single custom molded component. The membrane keeps the layout coordinated while the individual key faces can be shaped for their functions. Size, color, and marking options allow the interface to match the intended housing.

Develop the face area with the surrounding panel in mind. The part visible above the housing needs enough room for a finger and a clear legend, while the section underneath must align with the switch. Raised, recessed, printed, or color-filled identification can be selected according to the available space and how the controls are used.

Check that each key has sufficient clearance at its aperture and that the membrane is supported outside the moving areas. During assembly, avoid trapping an edge beneath a locating feature. Test the finished panel for independent operation of adjacent buttons, including keys near the outer perimeter. Keep the underside free of particles, and use gentle cleaning on the visible faces so dirt is removed without damaging the markings or disturbing the fit.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. Check that each key has sufficient clearance at its aperture and that the membrane is supported outside the moving areas.
Custom dimensions: The part visible above the housing needs enough room for a finger and a clear legend, while the section underneath must align with the switch.
Fit & assembly: Keep the underside free of particles, and use gentle cleaning on the visible faces so dirt is removed without damaging the markings or disturbing the fit.
Use & inspection: Raised, recessed, printed, or color-filled identification can be selected according to the available space and how the controls are used.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
