LED Backlight Membrane Switch

 LED backlighting membrane switch is an advanced Human-Machine Interface (HMI) that combines the best of LED illumination and membrane switch technology. Far more than a traditional switch, it is a comprehensive, integrated module that incorporates keypad functions, internal circuitry, graphical overlays, and a light source into a single unit.

How it works:

  When a user presses a button area on the graphic overlay, it flexes the top circuit layer through the cutout in the spacer. The conductive pad on the top layer makes contact with the traces on the bottom layer, completing the circuit and registering a keypress. The integrated LEDs are powered by separate traces within the circuit and can be illuminated through transparent windows in the overlay.

 Key Features

Ultra-Thin: With a typical thickness of less than 1 mm, these switches are ideal for products with limited space and can be installed on slightly curved surfaces.

Modern Aesthetics: The seamless, smooth surface is easy to clean and can be custom-designed with exquisite graphics, colors, and dynamic lighting effects (such as steady-on, breathing, or multi-color illumination), delivering a high-tech and aesthetically pleasing look.

Excellent Sealing & Resistance: The fully sealed construction provides robust protection against water, dust, oil, and chemical corrosion (achieving high IP ratings). This makes it perfectly suited for harsh environments found in medical, industrial control, and kitchen appliance applications.

Customizable Tactile Feedback: By incorporating different types of domes (e.g., metal or polyester domes), the switch can be engineered to provide distinct tactile feedback, from a crisp, audible "click" to a soft, linear feel.

High Degree of Integration: These switches are built for reliability and a long operational life, typically rated to endure over one million actuations.

High Durability & Long Lifespan: These switches are built for reliability and a long operational life, typically rated to endure over one million actuations.

Customization: LGF backlit switches offer extensive design flexibility, supporting various colors, brightness levels, and custom patterns to meet specific aesthetic and functional requirements.

Applications

Medical Equipment: Patient monitors, ventilators, infusion pumps, etc. which requires being sealed and easy to sterilize.

Industrial Control: CNC machine tools, instruments, automated equipment panels etc. which requires dustproof, waterproof, and anti-interference properties..

Home Appliances: Microwaves, dishwashers, coffee makers, smart kitchen appliances, etc., which enhance product quality..

Automotive Electronics : Central control panels, steering wheel controls, etc.
