What Is a Silicone Rubber Keypad? Benefits, Applications & Custom Options

Silicone rubber keypads, also known as elastomeric keypads, are flexible, cost-effective, and durable switching solutions widely used in industries such as medical, automotive, consumer electronics, and industrial control.

At Luen Fung Silicone Rubber Mfg., Co., we specialize in custom-designed silicone keypads to meet precise performance, aesthetic, and environmental demands.

What Is a Silicone Rubber Keypad?

A silicone rubber keypad is a type of switch made from compression-molded silicone elastomer. It features key shapes that collapse under pressure and spring back after actuation. Conductive carbon or metal pills under each key create an electrical connection on a printed circuit board (PCB) or membrane switch.

Key Benefits of Silicone Rubber Keypads

• Tactile Feel & Feedback: Offers excellent tactile response for user interaction, especially in mission-critical environments.
• Customizability: Supports various colors, legends, shapes, coatings (e.g., PU, epoxy), and backlighting options.
• Durability: Resistant to water, dust, extreme temperatures, and harsh chemicals.
• Cost-Effective: More economical than many mechanical switch options, especially for medium-to-high-volume production.
• Flexible Design: Compatible with dome switches, PCB circuits, and membrane circuits.

Common Applications:

• Medical Devices: Portable diagnostics, defibrillators
• Industrial Controls: Machinery, keypads on control panels
• Consumer Electronics: Remote controls, gamepads
• Automotive Systems: Dashboards, in-car entertainment systems
• Military Equipment: Rugged handheld radios and GPS units

Custom Options

• Backlighting: LED, EL, or fiber optic integration
• Coatings: PU coating for abrasion resistance, epoxy coating for gloss finish
• Printing: Laser etching, silk-screen printing, and spray painting
• Material Options: FDA-compliant silicone, flame-retardant silicone, translucent silicone
