Hello Amazon customer,

we recommend that you go directly to the Bosch product page Switzerland. The MUM5 is also listed on the homepage in Switzerland.

Our customer service in Germany is available to answer any questions you may have about the appliance, accessories or handling before and of course after purchase.
You can reach us by telephone from Mon-Fri between 8.00 and 18.00 hours.
You have the option of calling up the manufacturer profile for further contact options.

Best regards,
Your Bosch Home Team

We receive this kitchen machine from our supplier only with a DE power connection and enclose a CH power adapter with the item. Unfortunately, however, we cannot organise the machine with a fixed CH power connection.
