Many associations, which are active on a local, regional and country-wide level, consist of sections, cantonal associations and the Swiss umbrella association, the central association. The umbrella association unites several independent associations operating in the same or a similar business field. The relationship between section and umbrella association varies according to the organisation, which is defined in the articles of association. Either only the sections (partial associations) are members of the umbrella association, or the individual members are members of both the section and the umbrella association.
