Product Overview

A conductive silicone membrane keypad forms the flexible control layer of a custom keyboard or button assembly. The molded keys should correspond to the chosen circuit contact positions and the enclosure openings. Its geometry can be developed for remote controls, electronic equipment, or other defined control layouts.

The sheet needs support across the areas that establish the resting gap above the circuit. An unsupported section or a compressed margin can change how neighboring keys move. Review the complete stack of parts after the enclosure is secured. Every key should engage the intended contact and separate again without leaving another control partly depressed.

Printing and molded marking options allow the visible commands to match the contact layout. Check their orientation alongside the hidden locating features so the sheet cannot be mistaken for a reversed or similar version. Keep the underside clean during fitting and avoid dragging conductive areas across sharp surfaces. The circuit and molded component together determine electrical operation, including the response to successive or combined presses.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. The circuit and molded component together determine electrical operation, including the response to successive or combined presses.
Custom dimensions: The molded keys should correspond to the chosen circuit contact positions and the enclosure openings.
Fit & assembly: Check their orientation alongside the hidden locating features so the sheet cannot be mistaken for a reversed or similar version.
Use & inspection: Keep the underside clean during fitting and avoid dragging conductive areas across sharp 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.
