There are several technologies available for adding light to your membrane switch assembly:
- Popular as indicator lights, LEDs (light-emitting-diode) are very efficient and radiate very little heat.
- Single or bi-color
- Blue & white available
- Used under polyester graphic or rubber keypads
- An optical fiber is a glass or plastic fiber that carries light along its length. Fiber Optic panels are most commonly used where uniform lighting is required in larger areas.
- Pliable panel
- Powered by LEDs
- Long life
- Replaceable
- Used under polyester graphic or rubber keypads
- Electroluminescence (EL) is the phenomenon that occurs when a material emits light when exposed to an electric current, or strong electric field. EL is an alternative to fiber optic backlighting.
- Pliable panel
- Brighter light source
- Will not inhibit actuation force
- Used under polyester graphic or rubber keypads
- Greater design flexibility
- Tooling required
