are you looking for an electroluminescent panel for the switch panel?? Like in cars??
There are no manufacturers of those for aircraft. The lighting is supplied by an LED embeded in the panel, with a power supply, for all the lights.
In volume, these are inexpensive, the costly part is the regulated power supply. Again, in volume the cost is low.
Getting is approved would be very difficult.
There are people who provide electroluminescent panels, that can light up the switch panel.
