Product Overview
A membrane waterproof keypad for a game-control design needs its flexible control surface to work with the surrounding enclosure. The membrane may cover the key area, but water can still enter through an unsuitable perimeter, cable exit or other opening in the device. Any waterproof requirement must therefore be established for the complete assembly.
Game controls may be pressed repeatedly or in combinations. Evaluate the layout for the intended commands, including whether adjacent keys remain independently selectable. The membrane and its supporting structure should preserve the intended travel without one press pulling another control into contact.
Plan the perimeter seating and connection route before finalizing the visible button arrangement. A trapped edge can affect both fit and key feel after the housing is fastened. Check operation in the assembled control and use cleaning methods compatible with the surface and electronics. If the membrane develops a tear or begins lifting at an edge, address the damaged component rather than continuing to rely on its original coverage of the control area.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. The membrane and its supporting structure should preserve the intended travel without one press pulling another control into contact.
- Custom dimensions
- The membrane may cover the key area, but water can still enter through an unsuitable perimeter, cable exit or other opening in the device.
- Fit & assembly
- Check operation in the assembled control and use cleaning methods compatible with the surface and electronics.
- Use & inspection
- If the membrane develops a tear or begins lifting at an edge, address the damaged component rather than continuing to rely on its original coverage of the control area.
Photos illustrate structure or material only. A trapped edge can affect both fit and key feel after the housing is fastened. 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.
