Weird question about lighted rocker switches.

If it sends power to the terminals when active, just send that power to a relay that clamps device to ground when energized. It will save the switch (micro amps) and will give you your lighted active signal. They can be hidden and are very small, ie. 1inch. just match amp rating. can make a relay board or just buy a socket. A 2 pole switch or relay can turn on an indicator light also if the switch does not provide that.
