Product Overview
Conductive pills serve as contact elements within a molded keypad arrangement. The custom pill dimensions and placement need to align with the underlying circuit and the movement of the silicone keys. Any surface finish or coating on the keypad should be considered alongside that contact function.
The contact side needs a defined position relative to the board in the relaxed and pressed states. The housing, backing, and rubber geometry all influence that relationship. A coating intended for the visible surface should not be assumed suitable for the electrical contact area or allowed to interfere with the intended movement.
Handle the contact elements cleanly and keep oils or particles away from their working surfaces. Assemble the keypad in its intended orientation and test it with the enclosure secured. Check independent operation and release of each key, particularly near edges or fasteners where clamping can differ. The complete keypad and circuit determine the required electrical performance and service life, so those properties should be established for the finished construction rather than inferred from the presence of a conductive pill.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. The custom pill dimensions and placement need to align with the underlying circuit and the movement of the silicone keys.
- Custom dimensions
- The contact side needs a defined position relative to the board in the relaxed and pressed states.
- Fit & assembly
- Check independent operation and release of each key, particularly near edges or fasteners where clamping can differ.
- Use & inspection
- Handle the contact elements cleanly and keep oils or particles away from their working surfaces.

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.
