In many cantons there's an "error" allowance of 5 km/h when issuing a speed ticket. If the speed limit is 50, you won't get a ticket unless you were at 56 or more. This is done to account for car's speedometer inaccuracy. One principal difference is Swiss traffic controls, at least in French-speaking parts, is that they prevent intersections of traffic flows. E.g. you can't turn left on a green that allows going straight unless cars in the opposite direction are held by the red. That is, if you are following the signs and lights, you will simply not have a chance to run into another car going in some other direction.
