Detailed
Custom Silicone Rubber Keypads Engineered to Your Specification
A custom silicone keypad is a compression molded rubber assembly that combines key domes, tactile webs, conductive contacts and a pressure sensitive adhesive backing into one sealed interface. FromRubber engineers each layer against your enclosure, PCB contact pattern and operating environment, so the finished part drops into your assembly without redesign.
We have delivered 6532 custom projects and keep 7254 molds in stock, and we can start from a 3D file or from a physical sample when no drawing exists. Explore our full range of custom silicone keypads or send your requirement for an engineering review.
Full In-House Process
Tooling, molding, printing, etching and final inspection are completed inside our own two factories, with no outsourced steps between design and shipment.
Built Around Your Enclosure
Wall thickness, key height, travel and sealing are set to your housing and PCB layout, not chosen from a fixed catalogue of standard shapes.
Start From a Sample
Many suppliers require a 3D drawing before quoting tooling. We can reverse engineer tooling from a physical sample and adjust key parameters to fit your housing.
Design Specifications You Can Set
Every keypad we quote is defined by a small set of engineering parameters. Give us your target values and our engineers confirm what is achievable before tooling starts.
| Parameter | Production Range | Why It Matters |
|---|---|---|
| Hardness (Shore A) | 30 - 80 | Controls tactile feel, rebound and sealing pressure |
| Actuation Force | 150 - 400 g | Balances accidental activation against operator fatigue |
| Key Travel | 0.8 - 1.5 mm | Trade-off between tactile feedback and assembly thickness |
| Snap Ratio | Engineered to target feel | Defines how clearly the operator feels the switch close |
| Keypad Life Cycle | 1 - 5 million actuations | Sets service life for high-use equipment |
| Contact Resistance | Matched to your PCB contact pattern | Determines the detection margin of your circuit |
| Operating Temperature | Standard, high-temperature or low-temperature grades | Defines the environment the keypad can serve |
| Minimum Order Quantity | 1000 pcs | Entry threshold for a custom tooled part |
Tighter tolerances and dual-durometer constructions are reviewed case by case. Send us your drawing and running conditions and we will confirm the achievable window in the quotation.
Conductive Contact Options
The contact layer decides switching reliability. We produce four conductive options in house and select them by operating environment and reliability level rather than by unit cost alone.
Conductive Ink
Screen printed directly onto the keypad underside. Suited to thin structures and irregular key layouts where a printed contact layer keeps the assembly flat.
Carbon Pills
A carbon loaded silicone pellet bonded under each key. The standard choice for remote controls, instruments and control panels where contacts must stay stable over years of use.
Nickel and Gold Pills
Used where contact resistance must stay low and repeatable. Automotive and high-reliability programmes are specified with nickel or gold pills.
If you are comparing the main conductive methods of silicone keypads for a new design, send us your PCB contact pattern and our engineers will match the contact type, pill diameter and alignment tolerance to it.
In-House Manufacturing Capabilities
Keypad quality depends on how many steps leave the building. At FromRubber the entire chain runs inside our own plants, from tooling to final inspection, which keeps tolerances under one owner and removes the handover losses common to subcontracted production.

Tooling Held In House
Our own mold shop runs CNC machining for both silicone and plastic tooling. Sample molds are typically ready in 3 to 5 days and production molds in 10 to 12 days, which is why our development cycle runs about 30 percent faster than the usual lead time for the same scope.
Read more about our silicone molding and tooling capability.
Surface Finishing and Legend Options
Finishing decides how the keypad looks after two years of use. Choose the treatment to match the cleaning agents, UV exposure and abrasion the part will actually meet in service.
| Process | Result | Typical Use |
|---|---|---|
| Silkscreen Printing | Flat printed legends in multi colours | Standard non-backlit keypads |
| Ink Spraying + Laser Etching | Light transmitting legends with blocked background | Backlit keypads |
| Epoxy Dripping | Raised wear resistant surface | Control panels in harsh environments |
| Multi-Color Molding | Colour separation with clean joints | Remote controls and consumer devices |
| Electroplating / Silver Ink | Metallic appearance | P+R keys and premium enclosures |
| 3M Backing Adhesive | Ready to mount assembly | Electronics assembly lines |
Legend Durability Is Tested, Not Claimed
Printed legends are checked on our own abrasion equipment. A typical acceptance criterion is no breakthrough after 300 rubbing cycles with a 1 kg load, with 250 cycles applied at corner positions. Every batch is inspected against it before packing, and the results are documented per project and can be shared together with the quotation.
See how we answer the question of printing durability on silicone keypads and which abrasion standards apply.
What We Need to Start Your Project
Send these five items and our engineering team can return a quotation and a manufacturability review rather than a generic price list.
- 3D CAD file in STEP or IGES, or a physical sample if no drawing exists
- 2D drawing with critical dimensions and tolerance notes
- Estimated annual volume and first order quantity
- Operating environment, cleaning agents and required service life
- Assembly method: adhesive backing, plastic caps, brackets or over molding
Not ready to commit to production tooling? Ask for our custom silicone samples and we will quote a sample mold alongside the production quotation, so you can test fit and feel before the full tooling investment.
Two files is enough to get a real answer — a drawing or a photo of your sample.
Reviewed by an engineer, not a sales desk. No commitment to order.
Where These Keypads Are Used
Each application sets different priorities. Tell us the operating conditions and we will configure material, contact and finishing accordingly.
POS and Payment Devices
High daily keystroke counts, cleaning with alcohol based agents and stable contact resistance over a long service life.
Medical Devices
Sealed surfaces that tolerate repeated disinfection and easy to clean sealing geometry.
Automotive Controls
Wide temperature range, UV exposure and nickel or gold pill contacts for repeatable switching.
Industrial Computers and Instruments
Waterproof sprayed surfaces, higher actuation forces for gloved operation and abrasion resistant legends.
Remote Controls
Multi-colour molding, translucent legends and tactile feel tailoring across the whole key field.
Kitchen Appliances
Resistance to grease, steam and regular wiping without legend loss.
For a worked example in one of these segments, see our conductive silicone keypad for POS machines.
When a Silicone Keypad Is Not the Best Fit
Silicone handles most sealed tactile interfaces well, but it is not the right construction for every case. We would rather say so before tooling than after.
Very high cycle counts with a crisp metal click
If the interface must survive tens of millions of actuations and the operator expects a sharp metal snap, a metal dome or a mechanical switch assembly will outlast and out-feel a silicone web.
Flat panels with little or no key travel
Where the front panel has to stay very thin and the keys barely move, a membrane switch printed on polyester can be a better fit than a molded silicone layer.
Legends that change per unit or per language
Silicone legends are fixed at the moment of molding. If the interface needs different symbols per variant, or content that changes, a display or a replaceable overlay is more practical.
Continuous sealing across the whole enclosure
A silicone keypad seals its own key field. Where the full enclosure joint must be sealed, a separate gasket design is normally needed alongside the keypad.
Naming the constraint does not end the conversation. In most of these cases we still supply the silicone part, the gasket or the plastic housing next to it, and we will tell you which construction actually serves your product.

Frequently Asked Questions
What is the minimum order quantity for custom silicone keypads?
The standard minimum is 1000 pcs for a custom tooled keypad. Lower trial quantities can be discussed together with the sample mold, and the cost of tooling is quoted separately from the part price.
What design files do you need to start a project?
A 3D CAD file in STEP or IGES plus a 2D drawing is the fastest route. If you can also share the enclosure drawing and PCB contact layout, we can check wall clearance and contact alignment before tooling is cut.
What if I only have a sample and no 3D drawing?
Send the sample. Our engineers measure it, rebuild the drawing and adjust key parameters where the original has fit or feel problems. This is how we handled a Malaysian POS terminal project that other suppliers declined for lack of a 3D file.
How long do tooling, sampling and production take?
Quotation within 3 hours of receiving your files. Sample mold typically 3 to 5 days, production mold 10 to 12 days, with mass production scheduled after your sample approval.
Can you match custom colours, legends and backlighting?
Yes. Colour matching to your reference, multi-colour molding, silkscreen printing, epoxy dripping and laser etched legends for backlit keypads are all produced in house, together with 3M backing adhesive where the keypad is mounted directly to the housing.
Which conductive contact should I choose?
Conductive ink suits thin and irregular layouts, carbon pills are the general purpose choice for control panels and instruments, and nickel or gold pills are used where resistance must stay low and repeatable. Send your PCB contact pattern and we will recommend the contact type and pill size.
