Progressive switch interior lighting circuit

Use of a progressive switch, such as the Eaton 8860K4 permits the switch to have the usage off - on (green) - on (red)

The compass light is also illuminated whenever the interior light is either green or red

The night VFR lighting requirements call for the use of a dimmer

I will be using a PWM dimmer from Aircraft Spruce

I have provisioned the midsection interconnect wiring with enough connectivity to permit the compass light to be either dimmable or constant, by bringing both the input and output of the PWM dimmer to pins. The compass wiring loom is located in the fuselage, rather than running direct from the panel.
