LGF backlight membrane switch, membrane keypad:
Description:
LGF is a revolutionary new technique of adding illumination to text, icons and large areas of membrane switch graphics. Low power side firing surface mount (SM) LED's (Light Emitting Diodes) send light along the thin film (LGF).
The principle is analogous of fibre optic cable where light is transmitted along a cable or wire bouncing off the polished sides like a light pipe. The LBF is selectively printed with a texture to allow light to escape in the desired locations. It offers uniform brightness. It is less expensive than FO (Fibre Optic) backlighting and more durable than EL (electroluminescence) backlighting.
1) Maximum voltage: 50VDC
2) Maxinum current: 100mA
3) Contact resistaance: 0.5-10ohm.
4) Maximum loop resistance: 50ohm.
5) Minimum insulation resistance.: 100m. Ohm. At 100VDC
6) Switch power: 0.25-500mv
7) Material compression resistance: 1500VDC
8) Contact bounce: 10ms or less
9) Actuation force: 15-750gram-0.4mm
10) Tactile type: 0.4-1.0mm
11) Life expectancy: 1, 000, 000 times or more.
12) Flexility: Less 180
13) Operating temperature: -20 ~+60
14) Storage temperature: -40~+70
15) Humidity: : Less than 95%
