Adapting to the climate in Switzerland

Unless you're living high up in the mountains, the climate is no big issue in Switzerland. It is quite moderate. Inconveniences by snow in winter are minimal, as the Swiss are perfectly prepared to it. Delays in traffic and public transport do occur, but are marginal when compared to other countries.
You are expected to prepare yourself, too, for example, by having winter tires at your car in winter (and having show chains in your car whenever you are going up into the mountains). Winter tires are not mandatory, but many insurance companies will make problems when you are involved in an accident and did not have winter tires.
Autumn can come with so-called "inversion" in which cold air in the valleys cannot escape. It results in fog that can last for weeks and makes some people a bit moody.

Living in New Hampshire I figured the climate would be about the same. It is in the summer. A few weeks of hot but normally temperate. Nice cool breezes in the evening. But the winters aren't the same here in Lausanne. Rarely is there snow. Temperatures get down but not so far that I've ever needed to turn on the heat. Leave the thanks to that for the way buildings are constructed here!
