Is there a way to wire the lighting on an illuminated switch so that it's powered by a separate dedicated battery and NOT by the matrix encoder device that the switch is a part of?
I have a USB matrix encoder that only provides +5V, and all the common illuminated switches seem to require 12V, give or take. I think this would basically mean having two isolated, separate circuits, where the intersecting factor is some one (latching) switch. Is this possible?
Another alternative that I could go for is, picking a regular non-illuminated switch but having it control an externally powered indicator LED that makes up for the actual switch's lack of internal illumination.
