Coach Ottmar Hitzfeld has helped propel the Swiss up to sixth in the FIFA world rankings as the German led his team into the finals without losing a game in qualifying.
Along with an impressive showing in the preliminary stages, Switzerland also beat host nation Brazil in a friendly last August, and Deschamps is well aware of the danger that today's opposition has in their ranks.
"Switzerland is a team with a lot of quality. They have qualified easily in their group and did very well in their friendly games," the Les Blues trainer told a press conference.
"In their last 10 games, they won seven times and drew twice and had only one defeat against South Korea. They beat Brazil."
Both nations managed a victory in their opening Group E encounters, with France easing past Honduras last Sunday, while Hitzfeld and co needed a last-gasp goal from Haris Seferovic in order to beat Ecuador.
Tonight's encounter is scheduled to kick off at 8pm.
