Product Overview

Custom conductive silicone rubber keypads combine flexible key motion with electrical contact areas arranged for the product's circuit. The molded sheet, individual buttons, and supporting enclosure should locate those contacts consistently. Size, color, and geometry can be adapted to the required control layout.

Consider what happens when a key is pressed away from its center. The button may tilt, and its underside must still move within the range intended by the contact design. The surrounding rubber should support that motion without pulling another key or shifting the sheet. Assess the completed keypad assembly across the accessible pressing areas, including keys near the perimeter.

Material selection should reflect the environment in which the controls are used and cleaned. Conductive contact behavior belongs to the specified formulation or contact construction and its interface with the circuit. Keep those areas free from residue during assembly, and avoid stretching the keypad to correct a housing mismatch. After securing the enclosure, check that each key returns freely and that the visible layout remains aligned with the intended electrical positions.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. After securing the enclosure, check that each key returns freely and that the visible layout remains aligned with the intended electrical positions.
Custom dimensions: Size, color, and geometry can be adapted to the required control layout.
Fit & assembly: The surrounding rubber should support that motion without pulling another key or shifting the sheet.
Use & inspection: Material selection should reflect the environment in which the controls are used and cleaned.

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.
