Not for a 25€ speeding ticket but for bigger charges definitely and the German authorities will not take you in custody for speeding in Switzerland or France.
It is almost the same procedure as for foreign people speeding on the autobahn and getting caught right away. You either pay on the spot your fine or the police will hold you until you payor someone else pays for you.
