Product Overview

This silicone rubber keypad provides a molded input surface for a custom electrical control. The key arrangement and dimensions can be developed around the equipment housing, with color choices suited to the interface. Its role is to transfer a user's press to the switching structure beneath the rubber.

Review the front panel together with the internal board supports. A layout that is clear on a loose keypad may become crowded once the panel surrounds each key. Leave enough clearance for the key walls to flex and return without dragging against the openings.

Consider the equipment's normal viewing and operating position. Identification needs to remain readable, and frequently used keys should be reachable without pressing another control unintentionally. The rubber should also fit the expected cleaning routine for the finished equipment. During assembly checks, operate the keys after the housing is secured and compare their response across the whole layout. Keep the underside clean during servicing. Any change in key behavior after reassembly should prompt an alignment check before altering the rubber or the board contact.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. Leave enough clearance for the key walls to flex and return without dragging against the openings.
Custom dimensions: The key arrangement and dimensions can be developed around the equipment housing, with color choices suited to the interface.
Fit & assembly: Any change in key behavior after reassembly should prompt an alignment check before altering the rubber or the board contact.
Use & inspection: The rubber should also fit the expected cleaning routine for the finished equipment.

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.
