Product Overview
A numeric elastic keypad can be custom molded in silicone rubber to follow a specific number entry layout. The key dimensions and arrangement should suit the enclosure and the way the user reaches the controls. Color choices can distinguish groups while the physical spacing provides room for deliberate input.
Consider the complete entry task when setting the layout. Repeated movement between distant keys may reveal an awkward reach that is not obvious from pressing each button once. Check the pad with the underlying switches and housing installed, including the available travel at keys near an enclosure edge.
The rubber should return naturally without pulling adjacent buttons into contact. Select the finished compound for the handling and cleaning conditions, and keep the supporting regions free of trapped debris. During servicing, inspect for a shifted sheet or a corner pinched beneath the panel. A key that works on a loose pad but drags in the device needs its assembled clearance reviewed. Consistent positioning supports useful numeric input without relying on extra finger pressure.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Repeated movement between distant keys may reveal an awkward reach that is not obvious from pressing each button once.
- Custom dimensions
- A key that works on a loose pad but drags in the device needs its assembled clearance reviewed.
- Fit & assembly
- Check the pad with the underlying switches and housing installed, including the available travel at keys near an enclosure edge.
- Use & inspection
- Select the finished compound for the handling and cleaning conditions, and keep the supporting regions free of trapped debris.

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.
