Product Overview

Conductive elastomer buttons combine a flexible key with an electrical contact feature suited to the intended circuit. Their response should be checked through a complete press-and-release action, not only at the moment a button is held firmly down. The mechanical return and electrical release need to agree in the assembled device.

Evaluate presses from the center and from the normal edge positions used by an operator. Watch for an input that occurs only under excessive force or remains active after the key top starts to return. Seating, contact alignment and clearance beneath the key all deserve inspection before changing the rubber hardness.

ETOL can customize the molded structure and choose a conductive construction appropriate to the design, with color and legends developed around the visible controls. The electrical acceptance criteria should follow the device's circuit requirements rather than a general description of conductive rubber.

Keep the contact area free from oil and loose particles during fitting. If a sample behaves differently after the enclosure is fastened, examine the housing's support and compression points. Do not scrape the conductive surface to compensate for a mechanical mismatch. Recheck the complete input sequence whenever the board position or keypad geometry changes.

Material options
Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection
Silicone: 20–80 Shore A. Watch for an input that occurs only under excessive force or remains active after the key top starts to return.
Custom dimensions
Evaluate presses from the center and from the normal edge positions used by an operator.
Fit & assembly
If a sample behaves differently after the enclosure is fastened, examine the housing's support and compression points.
Use & inspection
Seating, contact alignment and clearance beneath the key all deserve inspection before changing the rubber hardness.

Photos illustrate structure or material only. If a sample behaves differently after the enclosure is fastened, examine the housing's support and compression points. 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.
