This architectural drawing is an Aviation obstruction light control panel design in AutoCAD 2D drawing, CAD file, and dwg file. The electrical gadget, which keeps tabs on the primary obstruction light's performance, is powered by the rated voltage input. A relay will direct the functioning of the secondary obstruction light if the primary beacon fails as a result of short-circuiting or disconnecting.
