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