Yep, this looks like a regular PAL machine indeed.
The small switch toggles between producing a modulated RF signal for System G and I. ("G" has been standard for mainland Western Europe. "I" has been used in the UK, Ireland, and a couple of other countries. "G" uses a 5.5MHz sound carrier gap; for "I" this is 6MHz. Also, "I" had slightly different frequency shaping. With a strictly "G" specific tuner in the TV, one loses the sound from an "I" RF signal... I mean it's not possible to tune both to video and sound at the same time. Honestly, I have no idea why toggling the switch produced white noise in your test.)
