Rappan spent almost all of his managerial career – which extended from 1932 to 1963 – coaching Swiss teams and the Switzerland national team. After his role as player-coach at Servette, Rappan became a full-time coach and joined
Grasshopper Club Zürich, managing the
Zürich club from 1935 to 1948, and winning five domestic league titles and seven cups. In 1948, he returned to Servette for a second period at the club, now as coach only. He remained there until 1957, adding one more league title and one cup to his palmares. After Servette, Rappan had a one-season spell at FC Zürich. From 1960 to 1963, he coached the Switzerland national team exclusively, and after this last period in charge of the national squad, he joined club
Lausanne-Sport, being their coach from 1964 to 1968, and winning one league title in 1965. After almost four decades of service in Swiss football, he returned to Austria to be the technical director of
Rapid Wien – his former club as a player – for the 1969–70 season. The system varied largely from the classic
2-3-5 formation and the WM, focusing in defense. The team would fold back into its own half and wait for the opponent's attack, conceding possession of the midfield. The system received the name of
verrou or "bolt". It has also been called "Swiss bolt". Reportedly, Rappan looked for a system that was less rigid and less dependent on individual talent than the WM. It relied on collective work, and gave the amateurs of the time a chance to compensate to some extent for their lack of skill. The defensive strategy of the bolt relied on a mixture of zonal and man-marking. It was the first system to play four players in defense, using one of them as a "security bolt" supporting the other three. With Rappan as its coach, Switzerland qualified to the World Cups of
1938,
1954 (where they beat
Italy and lost 7–5 to Austria in quarterfinals), and
1962. Rappan recorded three wins, one draw, and six losses as a coach in World Cup finals tournaments. His last match as Switzerland's coach was on 11 November 1963 against
France in
Paris, a 2–2 draw. ==After retirement==
