Product Overview
A PCB circuit silicone keypad should be evaluated with the board supported as it will be in the finished device. A board held loosely during a bench trial can move when a key is pressed, changing the apparent travel and response. The keypad and its supporting structure therefore need to be checked together.
Identify the board mounting points and the space beneath the key contacts. Confirm that the front housing does not force the rubber toward a bowed or misplaced board. Where keys are spread over a wide area, evaluate those between mounting points as well as those close to a support.
Custom key structure, hardness, color and marking are available from ETOL. The approved operating response should be established in the assembled configuration, not by adjusting the feel while the board is free to move.
During fitting, keep the contact side clear of foreign material and secure the board using its specified mounting arrangement. Operate the keys after closing the housing and look for differences across the layout. If behavior changes when a fastener is tightened, inspect the stack of components and available clearance before changing the keypad geometry. This helps distinguish a support problem from a molded-key problem.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. A board held loosely during a bench trial can move when a key is pressed, changing the apparent travel and response.
- Custom dimensions
- The approved operating response should be established in the assembled configuration, not by adjusting the feel while the board is free to move.
- Fit & assembly
- If behavior changes when a fastener is tightened, inspect the stack of components and available clearance before changing the keypad geometry.
- Use & inspection
- A PCB circuit silicone keypad should be evaluated with the board supported as it will be in the finished device.

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.
