Product Overview
Conductive silicone function key buttons can be custom molded for the control positions of an electronic product. The operating face, flexible section, and contact arrangement need to align with the housing and electronics. Where the design also needs moisture protection, the retained perimeter must be considered as part of the assembled interface.
Support the button base without restricting the region intended to move. A local clamp point can affect travel, while an uneven outer seat can leave an unintended path around the rubber. The shape and material should therefore be developed with the complete enclosure rather than only the visible key face.
Evaluate operation after final assembly. Check intentional presses from the positions users are likely to approach, and confirm that the button returns fully without remaining against the contact. Device-level protection depends on all relevant joints and openings and should be assessed under the intended conditions.
During installation, keep conductive regions free of contamination and ensure the button is correctly located over its circuit position. If the housing is reopened, restore the original seating arrangement before checking operation again. Clean the exposed surface using the finished product's intended care method.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Check intentional presses from the positions users are likely to approach, and confirm that the button returns fully without remaining against the contact.
- Custom dimensions
- During installation, keep conductive regions free of contamination and ensure the button is correctly located over its circuit position.
- Fit & assembly
- A local clamp point can affect travel, while an uneven outer seat can leave an unintended path around the rubber.
- Use & inspection
- Clean the exposed surface using the finished product's intended care method.

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.
