Our Backlit Membrane Switch Types

Our membrane switch backlighting solutions include:

  • MaxFilm proprietary membrane switch backlighting
  • Traditional LED backlighting
  • Fiber optic lighting
  • Electroluminescent lighting

MaxFilm Backlight Membrane Switch

Not only does our backlighting process create a more durable illumination to other membrane switch backlighting techniques, it also allows for greater flexibility during design. We are able to place MaxFilm on virtually any switch product needed. In addition, multiple colors can be specified.

  • Durable Construction
  • Multiple Colors Available
  • Low Energy Needs
  • Greater Luminous Output Than Fiber Optics
  • Typically Lower Cost than Other Lighting Options

MaxFilm Lighting Applications

  • Low light environments
  • Energy efficient products
  • Lower cost interface modules
  • Consumer
  • Light industrial

LED Membrane Switch Keypads

Standard LED technology produces clean clear light with very low energy needs.  Like the ALMAX  MaxFilm backlighting which typically utilizes an LED light source, traditional LED lighting provides durable backlighting, creating excellent LED membrane switch keypads.

  • Durable construction
  • Multiple colors available
  • Low energy needs
  • Greater luminous output than fiber optics

LED Lighting Applications

  • Low or no light environments
  • Continuously lit interfaces
  • Energy efficient products

Fiber Optic Membrane Switch Backlighting

Fiber optic backlighting technology gives you high light illumination. You can integrate fiber-optic technology into nearly any membrane switch or product.

  • High Light Output
  • Low Energy Needs

Fiber Optic Applications

  • Low or no light environments
  • Energy efficient products

Electroluminescent Backlighting Membrane Switches

Electroluminescent, or EL lighting, can be integrated into membrane switches, flat panel displays and other electronic interface assemblies.  Virtually any size electronic interface can be lit using EL technology.

Benefits Of Electroluminescent Backlighting

  • Low or No Light Environments
  • Thin Form Factors
  • Green Products

Electroluminescent Applications

  • Low or No Light Environments
  • Thin Form Factors
  • Green Products

Downsides Of Electroluminescent Backlighting Membrane Switches

  • EL Lamp requires AC voltage thus requiring DC to AC inverter & control circuit.
  • EL phosphor has a 3000-hour high-life and brightness dims gradually to 50%.
  • Colors are limited to white, blue, and yellow/green.
  • Much higher cost than LED solutions.
  • Added EL lamp layer will increase actuation force and reduce the tactile sensation of buttons.
