[1] He then moved on to lower tier CS La Tour de Peilz and stayed there for nine seasons.

Jaccard was called up to the Swiss national team in the 1933–34 season and played in the 1934 FIFA World Cup.

[2][3][4] After returning from Italy he was surprised by the fact that the club had transferred him to FC Montreux-Sports without him being involved or even knowing about it.

[1] Jaccard joined Basel's first team, with German trainer Alwin Riemke, in their 1935–36 season.

[5] He scored his first goal for Basel on 29 March 1936 in the away game against Young Fellows Zürich, where his team was beaten 2–4.

Only four consecutive victories towards the end of the campaign lifted the team to finish in joint second-last position in the league table.

The replay was played in the Stadion Neufeld in Bern on 20 June 1937 and ended in a 1–0 victory for Basel, and so they prevented relegation.

For the 1948/49 season Jaccard was appointed manager of Cantonal Neuchatel in the Nationalliga B, the second highest tier of Swiss football at that time.
