Product Overview

Conductive carbon pill rubber keypads place contact elements beneath custom molded operating faces. For a remote control, the visible layout and the circuit positions should be developed together. A large or offset button face may require a different supporting geometry from a smaller neighboring key even when both share the same mat.

Use the circuit pattern and enclosure locating features as the references for alignment. The rubber should settle into position without stretching between those points. Each carbon pill needs to approach its intended contact through the movement established by the button and surrounding web.

Test the keypad in the closed remote housing, including presses near the edges of broad keys. Check that one action does not move an adjacent button out of its resting position. Keep the conductive regions free from handling residue during assembly. Before fastening the case, make sure the mat is flat and every key is free within its opening. If servicing requires removal, preserve the orientation and recheck the complete control sequence after the keypad is refitted.

Material options: Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. Each carbon pill needs to approach its intended contact through the movement established by the button and surrounding web.
Custom dimensions: Before fastening the case, make sure the mat is flat and every key is free within its opening.
Fit & assembly: Check that one action does not move an adjacent button out of its resting position.
Use & inspection: If servicing requires removal, preserve the orientation and recheck the complete control sequence after the keypad is refitted.

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.
