Questions about Value Power cable Switzerland T12 to C13

It should fit, it's a normal appliance plug, I have an older Waeco cooler, the plug fits perfectly. It is a 3-pin plug like the ones used for many 230V devices (printers, coolers, monitors, desktops, etc.).

If the power supply unit was purchased from Digitec and the power plug does not fit... Digitec is obliged to supply electrical appliances with a Swiss plug. If the unit comes with a foreign plug, a suitable replacement cable should be supplied if the mains cable is pluggable or alternatively a suitable adapter if the mains cable is permanently connected. 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.

Yes should fit. If the issue is that Digitec has supplied the power supply without a suitable cable or a non-suitable plug. Digitec must supply a cable with a Swiss plug free of charge. Simply complain.

Here is the website of the FCA (Federal Customs Administration). I assume you have it listed somewhere. https://www.ezv.admin.ch/ezv/de/home/information-firmen/zolltarif---tares.html

This is a power cable...

Hardly. Switzerland probably simply refers to the information that it is used here;)

Give it away on Tutti and make someone happy...

Eh?
