Silicone Keypad Used in Industrial Equipment: Why Custom Design Matters for Control Panels

In factories, control panels must work flawlessly—even in heat, dust, oil, and gloves. That’s where silicone keypads stand out.

Silicone keypads in industrial equipment offer durable, chemical-resistant, and glove-friendly interfaces tailored for tough environments and repetitive use.

I’ve worked with clients in automotive plants, food processing lines, and heavy machinery industries. Their common challenge? Creating keypads that survive extreme conditions while remaining easy to operate. Here’s how we solve it with silicone keypad customization.

Why is silicone ideal for industrial keypads?

Industrial environments demand materials that are tough, flexible, and weather-resistant.

Silicone is resistant to high and low temperatures, UV exposure, moisture, and chemicals. It also retains flexibility over time, making it ideal for industrial keypads.

Unlike plastic buttons that crack under pressure or fail in cold, silicone maintains elasticity and bounce even at -40°C or over 200°C. It can withstand oil spills, solvents, and direct sunlight. This makes it the go-to choice for factory and outdoor control systems.

Key features include:

• Long service life (up to 1M presses)
• Customizable tactile feedback
• Excellent sealing capabilities for IP-rated designs

This is why silicone is found in nearly every reliable industrial panel today.

How are keypads designed for glove use and safety?

Operators wear gloves, work in dim light, and need fast response. Design must follow function.

Industrial keypads are designed with larger key spacing, strong tactile force, and visual cues to support safe, efficient operation even with gloves.

In production environments, operators might press keys thousands of times a day. Keys must be easy to locate and activate without needing delicate touch. We design for:

• High actuation force (180–250g) to avoid accidental presses
• Oversized keys and deep grooves for gloved fingers
• Color-coded legends for emergency or priority actions
• Backlighting or contrast printing for low-light environments

These features reduce operator error and improve safety during fast-paced operations.

What coatings and finishes are used in harsh environments?

The keypad surface must endure more than just finger presses—it must survive chemicals, abrasion, and UV rays.

Industrial silicone keypads use PU coatings, epoxy domes, and matte textures to protect the surface from wear, solvents, and sunlight.

For harsh environments, the base silicone isn’t enough. We apply:

• Polyurethane (PU) coatings for abrasion and solvent resistance
• Epoxy-topped keys for glossy, labeled areas
• Laser-etched legends that won’t fade or rub off
• Matte textures that improve grip and reduce glare

These treatments extend the keypad’s lifespan even under daily abuse.

How is sealing handled for waterproof and dustproof keypads?

Factory environments are full of dust, fluids, and moisture. The keypad must be sealed tight.

Silicone keypads for industrial use often include sealing skirts, integrated gaskets, and membrane overlays to meet IP65, IP67, or higher ratings.

We design integrated sealing systems in the mold itself. These include:

• Perimeter lips that press against the panel housing
• Built-in O-ring ridges that seal against metal or plastic
• Silicone skirts that prevent ingress around the key stem

These seals help the keypad qualify for high ingress protection levels:

We’ve helped clients pass their IP testing with molded-in seals that hold up in the field.

Can the keypad be integrated with electronics?

Yes—and it saves space and improves reliability.

Conductive silicone pills and carbon contacts allow keypads to interface directly with PCBs, eliminating the need for separate buttons or switches.

We mold conductive pads under each key, typically made from carbon or gold-filled silicone. When pressed, they close a circuit on the PCB. This approach is:

• More compact
• Fewer moving parts
• Easier to waterproof

We also support:

• Embedded LEDs for indicator lights
• Integrated domes for better click feel
• Multi-layer silicone for dual-hardness structures

This makes keypads smarter, more compact, and easier to install.

What are the common testing requirements?

Industrial keypads are only as good as the tests they pass.

We perform lifecycle tests, chemical resistance tests, and temperature cycling to ensure industrial keypads meet real-world stress conditions.

We don’t just mold and ship—we verify every design. Key tests include:

• Cycle life testing (up to 1 million presses)
• Tactile force consistency
• UV and weather aging
• Chemical immersion tests
• Ingress protection verification

This ensures your keypads survive the harshest industrial conditions.

Conclusion

Custom silicone keypads give industrial equipment the durability, feedback, and safety it needs. With the right materials, sealing, and testing, they become a trusted part of any control panel—built to last and easy to use.
