Switzerland doesn't really have liberal gun laws. Ex-conscripts can keep their service weapon at home, but it's tightly regulated (ammos are sealed and aren't to be open except in case of need). You can't buy a gun in a supermarket the way you can in a Walmart in the US, or open/conceal carry a gun.

Gun ownership is high due to more or less half the population serving in the army, and the laws are probably more liberal than in neighbouring European countries, but you can't compare it in any way to the US.
