The button must be pressed continuously during the shredding process. As soon as you release it, the appliance stops. There is no on/off function, only a momentary button.

Yes, the lid is made of plastic.

I haven't tried it yet. But it is possible to process hazelnuts into butter as long as you have a powerful kitchen appliance such as a high-performance blender or food processor. The process is relatively simple: 1. roasting: roast hazelnuts briefly in the oven (about 10-15 minutes at 180 °C) to remove the skins more easily and intensify the flavour. 2. peeling: Place the roasted nuts in a kitchen towel and rub to remove the brown skin (this is optional, but will affect the consistency and colour). 3. blending: Process the nuts in a high-powered blender or food processor. First crumbs are formed, then a paste, and finally the mixture becomes creamy due to the released oils. 4. refining: Optionally, a little salt, sugar or vanilla can be added if desired. It takes a few minutes and requires patience, but the result is a creamy hazelnut butter. You can pass this on in your answer!

No, linseed does not work. I use a coffee grinder for this - it works perfectly!

Hello it comes with 2-pole plug which is fine for Swiss outlets too.

If the ice cubes are not too large, it should be possible.
