Nevermind, that didn't work at all for me.  However, I put your code
(more or less) into an instrument I have here and it did work under OSG.
The AvionicsToggle is a toggle switch model taken from
Aircraft/Instruments-3d/controls/switch-large-flat.ac.  It rotates with
the boolean property value as well.  I last built Simgear/Flightgear on
31 Aug and am using OSG 2.0:
