Essentially no one even thinks of getting a gun for self defence. There also has never been an idea that guns are for defending yourself against your own government here.
There's no need for a military culture, when the government has already mandated it for you.
Not that it isn't popular:
>On September 22, 2013, a referendum that aimed to abolish conscription was held in Switzerland. However, the referendum failed with over 73% of the electorate voting against it, showing strong support for conscription of men in Switzerland.
In the absence of that mandate, there would be a vacuum in which citizens suddenly have self-interest in promoting voluntary readiness, which is implemented culturally.
I'm not sure your source but you should double-check it; it's entirely incorrect.

Says who? Are you Swiss?
I believe that's the security that us Americans (I imagine your sneer with that) feel by being armed.
Isn't it that the Swiss are all armed as well? They seem to have fared rather well in a 20th century Europe fraught with conflict. Tell me that's a coincidence with absolutely no correlation to their pro-gun culture.
