L'invention concerne un contact enfichable (1) pour la mise en contact électrique d'une carte de circuit imprimé (2) par enfichage du contact enfichable (1) dans un trou de contact (3) de la carte de circuit imprimé (2). Le contact enfichable est pourvu de deux branches de contact (4, 5) élastiques l'une par rapport à l'autre, d'une zone de connexion (6) et d'une zone de liaison (7) reliant les deux branches de contact (4, 5) entre elles et ces dernières à la zone de connexion (6), le contact enfichable (1) étant découpé à partir d'un matériau plat métallique et cintré. Le contact enfichable selon l'invention (1) permet, en dépit de la faible épaisseur du matériau plat, une mise en contact sûre par le fait que les deux branches de contact (4, 5) présentent respectivement une première partie (4a, 5a) et une deuxième partie (4b, 5b) adjacente à la première partie, dans le sens d'enfichage (E) du contact à enficher (1). Les deux branches de contact (4, 5) sont cintrées à partir du plan de la zone de liaison (7) de sorte que la zone de liaison (7) et les premières zones (4a, 5a), adjacentes à la zone de liaison (7), des deux branches de contact (4, 5) forment conjointement un contour en U. Une zone de mise en contact (4c, 5c), assurant la mise en contact du trou de contact (3) à l'état enfiché, est formée respectivement sur les côtés extérieurs opposés des deuxièmes parties (4b, 5b) des deux branches de contact (4, 5).
