If you work in northern italy the nearest dropzone in switzerland would be "paracentro locarno". It's quite expensive but the view and the dropzone in generall is great. (www.paracentro.ch)
If you travel longer and want to see a bit of switzerland I can recommend "Fallschirmgruppe Sittertal" in the north-eastern part of switzerland. (www.skydive-ostschweiz.ch)
I'm sure all the other dropzones are great too but I've never been there.
