Membrane Switch 0109

Many hand held equipment use LEDs for backlight. And we can design and assemble LEDs inside membrane switch. It would save lots of space and cost. Membrane switch with LEDs is the economical solution for switch backlighting. We can design LEDs for backlight buttons, symbols or icons. It would only need DC 3V to drive a LED, the best way to save energy in the project design. We can combine LEDs with light guide film, it could backlight the entire surface, this could increase the flexibility of design. With the design of water proof structure, membrane switch with LEDs can be installed in the outdoor equipment.
