Product Overview
A silicone printing numeric membrane keypad combines a flexible button arrangement with printed number identification. The layout can be customized for an electronic interface, with dimensions, hardness, and colors selected to suit the enclosure. Clear legends help users follow the number sequence, especially where the controls occupy a compact area.
Plan the printing around the actual button faces. Character size, placement, and contrast should remain readable in the normal viewing position, including when nearby fingers partly cover the keypad. A legend placed too close to a curved edge may be less useful than one centered on the effective touch area.
The printed surface is only one part of the interface. Each button still needs appropriate clearance and support so that entering a sequence feels predictable. Test movement between rows and columns after the keypad is installed in its housing, and check that repeated presses do not catch a neighboring key.
During assembly, avoid rubbing the printed faces against unfinished housing edges. Clean the keypad with a method compatible with the finished markings and electronic device. If the mat is removed for repair, keep it flat and preserve the locating features that establish its alignment.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Test movement between rows and columns after the keypad is installed in its housing, and check that repeated presses do not catch a neighboring key.
- Custom dimensions
- Character size, placement, and contrast should remain readable in the normal viewing position, including when nearby fingers partly cover the keypad.
- Fit & assembly
- A legend placed too close to a curved edge may be less useful than one centered on the effective touch area.
- Use & inspection
- If the mat is removed for repair, keep it flat and preserve the locating features that establish its alignment.

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.
