Abstract

La présente invention concerne un contact par ressort de pression (9) placé dans un boîtier (6), constitué d'un matériau en bande et comprenant une région de contact (10) permettant le contact d'un élément conducteur, notamment d'une piste conductrice ou d'une barre conductrice, ainsi qu'un bras de ressort (27) qui s'étend entre un contre-appui, de préférence situé dans le boîtier (6), et la région de contact (10). Le bras de ressort (27) est divisé par plusieurs zones de flexion et/ou pliages en au moins deux zones de ressort (18, 19) situées l'une au-dessus de l'autre au-dessus de la région de contact dans la direction verticale.
