At its core the modern Swiss political system was modelled after the US, albeit with changes that made it better suited for the Swiss landscape: Splitting executive power to 7 ministers (because Swiss just generally don't trust anyone enough to give full presidential power) and adding direct democracy at national level [1]. Later, Switzerland also changed from majority (as the US still uses) to proportional elections. In general, the Swiss political system is much more dynamic, with the constitution being constantly amended.
That's what I meant with 'mini-US' - culturally it's certainly not super close, but I'd also say it's a bit closer to the US than other Western European countries, with the economy being a fair bit more 'liberal' (in the classic sense, i.e. more freedom to businesses with lower taxes and weaker worker protections), but it's somewhere in the middle between Germany and the US in those regards.
