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
