The "On" switch of the network where in the air defenece bunker. It was
only marked with "På" (Swedish for On) with no further markings. It was
designed for when the soviet bombers comes, at least they should loose
their Chayka guidance.
I knew one of the folks that where boss over the system, was to his
funeral recently. He also worked hard to get the classified material and
make a public report out of it. Time to refresh your swedish, as I doubt
any translations exist in public.
