You can of course be satisfied with an adapter. However, I would recommend that you replace the entire cable with one that has a Swiss plug. There are only advantages. You can get the cable free of charge from Digitec if you point out their mistake.

Digitec (or any other Swiss retailer) is obliged to supply electrical appliances with a Swiss plug. If the appliance is supplied with a foreign plug, a suitable replacement cable should be supplied if the mains cable is pluggable, or alternatively if the mains cable is permanently connected, a suitable adapter should be supplied.
If the appliance is delivered without a suitable plug, complain to the customer service and insist on a cable or an adapter, free of charge.
