DC-3 Swap OBS Compass Rose Selector Switch is Toggling NAV Compass Light

Do you have the same issue if you follow the OP’s steps to reproduce it?

yes

Provide extra information to complete the original description of the issue:

The "Swap OBS Compass Rose” switch does not switch between Nav1 & Nav2 but instead switch on/off the illumination of the compass rose as explained by OP. Nav1 is selected by default.
Happens with both classic and retrofit versions.
