Product Overview
A flexible silicone rubber keypad can combine multiple buttons and their connecting sheet into one molded component. That flexibility helps the part follow its designed mounting arrangement, but it also makes the way the enclosure supports the sheet important. Unsupported areas may move when a key is pressed, changing how the control feels and how accurately it operates.
Locate the keypad positively in relation to the board and panel. Clamping should hold the intended support areas while leaving the button webs free to deform. Excessive compression at the perimeter can distort the sheet, and a locating feature that stretches the part into position may shift the button centers away from their openings.
Inspect the assembly first with the housing lightly closed, then at its normal fastening condition. A difference in key return or operating feel can point to uneven restraint rather than a problem with the visible button itself. When handling the loose part, support it across its body instead of suspending it from a protruding key. This protects the narrow flexible sections before the keypad reaches its final support structure.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Excessive compression at the perimeter can distort the sheet, and a locating feature that stretches the part into position may shift the button centers away from their openings.
- Custom dimensions
- A difference in key return or operating feel can point to uneven restraint rather than a problem with the visible button itself.
- Fit & assembly
- Clamping should hold the intended support areas while leaving the button webs free to deform.
- Use & inspection
- Inspect the assembly first with the housing lightly closed, then at its normal fastening condition.

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.
