I opened the attachment, @Alpenrose666. It is certainly an action-packed itinerary. Although you can adjust your daily schedule to accommodate as little or as much as there is time for them, these things stick out for me:
Day 2: Chillon castle / Cable car / Lavaux vineyard terraces
(a) Allow a couple of hours for Chillon castle, then additional time to get to between Montreux and Chillon. Villeneuve above Chillon is also very pretty so you might consider spending time there.
(b) Cable car -- do you mean the cog railway to Rochers-de-Naye? Or the Mont Pélerin funicular above Vevey? With either, you will fill the remainder of your day.
(c) Lavaux vineyards -- these are everywhere, and you will see plenty from the train en route to Montreux. There is a 35 km hiking route between Chillon or Montreux and Lausanne, but you won't have time for this.
Day 16: Travel from Locarno with a whole lot of activities before departing from Malpensa
I think you are seriously over-reaching here. Just make sure that you are in a position to get on a train at Bellinzona no later than 4:00pm, if not earlier, to make your flight.
