A conducting spring (102) for exerting a biasing force against a test button (22) to open a circuit interrupter test circuit (84). The spring (102) includes a one-piece, elongated cantilever (104) having a first (106) and second (110) end. The cantilever (104) is formed from an electrically conducting material. One of the cantilever ends (106) is adapted to directly secure to a first terminal (44) of the test circuit (84). The other cantilever end (110) is adapted to directly and reversibly contact a second terminal (126) of the test circuit (84). The spring (102) also includes means for resiliently flexing the second end (110) of the cantilever (104) in relation to the first end (106). The flexing means (134) is integrally formed with the cantilever. Also provided is a ground fault circuit interrupter and a ground fault circuit module (84) for protecting a circuit interrupter with a push-to-test feature (22).

Ressort conducteur (102) exerçant une force de rappel sur le bouton d'ouverture (22) d'un circuit de contrôle (84). Ledit ressort (102) présente une partie allongée en porte-à-faux (104) en matériau conducteur présentant une première extrémité (106) et une seconde (110). La première extrémité (106) est conçue pour se raccorder directement à une première borne du circuit de contrôle (84), et la seconde (110), pour être mise en contact direct et réversible, avec une seconde borne (126) du circuit de contrôle (84). Le ressort (102) comporte en outre un moyen de fléchissement élastique de la seconde extrémité (110) du porte-à-faux (104) par rapport à la première (106), ledit moyen (134) formant partie intégrante du porte-à-faux. Il est également prévu un interrupteur de défaut de terre et un module de circuit de défaut de terre (84) de protection du coupe-circuit du type "poussoir de contrôle" (22).
