Product Overview
A PCB keypad provides a flexible silicone control surface designed around a matching printed circuit board. The molded keys, contact positions and locating features should agree with the board layout and front housing. The board is part of the fit definition rather than only a surface placed beneath the rubber.
Check the distance between the board and the visible keys after the enclosure is secured. Support posts or fasteners can influence that spacing across the layout. Each key needs its intended resting clearance and movement without the panel holding it partly depressed.
Align the common keypad before testing individual buttons. A shifted edge can move several contacts together, while a warped support can make one area respond differently from another. Keep the underside clean and avoid introducing adhesive near the switching region during assembly. During service, restore the original board seating and fastening conditions before judging a key fault. A revised board or enclosure requires a corresponding fit review, even if the printed function layout is unchanged. The replacement keypad should preserve both the visible controls and the contact geometry that operates the intended circuit.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. A PCB keypad provides a flexible silicone control surface designed around a matching printed circuit board.
- Custom dimensions
- The molded keys, contact positions and locating features should agree with the board layout and front housing.
- Fit & assembly
- Support posts or fasteners can influence that spacing across the layout.
- Use & inspection
- The replacement keypad should preserve both the visible controls and the contact geometry that operates the intended circuit.

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.
