Product Overview

Transparent silicone rubber keypad buttons combine a visually open material choice with conductive features in the intended input arrangement. The conductive region and any underlying board will influence what can be seen through the button. Transparency should therefore be evaluated with the actual construction rather than assumed to produce a uniformly clear or illuminated key.

Coordinate the molded thickness, contact position and visible artwork with the housing. A clear-looking button still needs the correct travel and rest gap above its electrical target. The surrounding panel must leave the flexible sections free to move while maintaining registration.

Check both appearance and operation after assembly. Any lighting effect depends on the complete optical arrangement, and no particular contact resistance is established by the product category. Handle the visible surface carefully to avoid scratches and keep the underside contact areas free of residue. During reassembly, restore the locating features so a change in board or sheet position does not alter the button's intended electrical contact or visible alignment.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. A clear-looking button still needs the correct travel and rest gap above its electrical target.
Custom dimensions: During reassembly, restore the locating features so a change in board or sheet position does not alter the button's intended electrical contact or visible alignment.
Fit & assembly: Coordinate the molded thickness, contact position and visible artwork with the housing.
Use & inspection: Handle the visible surface carefully to avoid scratches and keep the underside contact areas free of residue.

During reassembly, restore the locating features so a change in board or sheet position does not alter the button's intended electrical contact or visible alignment. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

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.
