Product Overview
Silicone rubber key covers provide a molded finger contact over an individual control. Their shape needs to suit the switch and enclosure beneath them, with sufficient clearance for movement and a supported stationary area. A cover should not be treated as mechanically suitable simply because it fits over the visible switch top.
Define the assembly height, aperture geometry, and locating features together. Check whether the cover changes the switch's available travel or remains under compression when the panel is closed. A single control can still require careful orientation if its underside is shaped differently from its visible face.
Material compliance and mechanical operation are separate requirements. Where RoHS compliance is required, the selected formulation and finished component need to meet the applicable project requirements for the supplied configuration. Evaluate the assembled control for activation and free return. During handling, protect thin flexible areas and keep the underside clean so that the fitted cover can move as designed after installation or service.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Check whether the cover changes the switch's available travel or remains under compression when the panel is closed.
- Custom dimensions
- Define the assembly height, aperture geometry, and locating features together.
- Fit & assembly
- Evaluate the assembled control for activation and free return.
- Use & inspection
- During handling, protect thin flexible areas and keep the underside clean so that the fitted cover can move as designed after installation or service.
Photos illustrate structure or material only. your assembled clearance determines the cover design, including whether the panel leaves the button free to return. 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.
