Helvetica is a font, definitely not the proper name of Switzerland. https://fr.m.wikipedia.org/wiki/Helvetica
You’re probably thinking of Helvetia, which is neither the real name of Switzerland as it is an allegorical figure which represents Switzerland.
If you want the real official name of Switzerland, then you’ll have to get it into one of the official languages:
- Confédération suisse in French
- Schweizerische Eidgenossenschaft in German
- Confederazione svizzera in Italian
- Confederaziun svizra in romanche
On English it would be the Swiss confederation, or… Switzerland in short.
But that’s something that I witnessed change since the 80’s and makes the electronic crappier, it’s the fact that appliances in the 70’s-90’s were incredibly easy to fix. It was not rare for the manufacturer to even give schematics in the user’s manual. There were shops to repair stuff everywhere and it was something approachable by anyone who could hold a soldering iron.
