Product Overview

Flexible rubber silicone keypads provide custom molded controls within a shared elastomer component. Flexibility allows the keys to move, but the surrounding sheet still needs defined support and location. Its role is to keep the control group aligned while each key performs the intended press and release.

Review the spaces around and between the buttons. The sheet should not be stretched across mismatched locating points or left folded beneath the enclosure. Local distortion can change more than one key's resting position. Check the assembly after fastening and include presses across neighboring controls to confirm that their movements remain independent.

Size, color, and printed or molded markings can be customized for the interface. The selected material should suit the actual use conditions. During service, retain the specified orientation and supports when refitting the keypad. If a section moves unexpectedly, inspect the mechanical seating and clearance rather than assuming greater material softness will improve the operation of the complete control group.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. Check the assembly after fastening and include presses across neighboring controls to confirm that their movements remain independent.
Custom dimensions: The sheet should not be stretched across mismatched locating points or left folded beneath the enclosure.
Fit & assembly: If a section moves unexpectedly, inspect the mechanical seating and clearance rather than assuming greater material softness will improve the operation of the complete control group.
Use & inspection: During service, retain the specified orientation and supports when refitting the keypad.

Photos illustrate structure or material only. Flexibility allows the keys to move, but the surrounding sheet still needs defined support and location. 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.
