Fibre Optic Backlighting

Thin flexible fibre optic panels are located over domes in switches and keypads, maintaining positive tactile feedback while guaranteeing no degradation in brightness. The fibre optic panel never needs replacement and is so effective in uniformly spreading out the light from a single LED that it can cover up to approximately 100mm in width and 120mm in length. In addition, no heat or EMI is generated that can interfere with switch operation.
