Patent ID: 7271987

Claim:
A grounding fault circuit interrupter, including a housing, a trip means, and a control circuit, characterized in that it further comprises a pair of static contact pieces fixed on the housing; a pair of load contact pieces fixed on the housing; a pair of slide frames; a pair of movable contact pieces fixed on the slide frames respectively, which are resiliently movable and each has one end connected to conductive pieces through conductive strips, the conductive pieces welded on the circuit board respectively and passing through a sensing transformer and a neutral transformer, said pair of slide frames resiliently and movably mounted on a coil bracket; wherein when the static contact pieces are in contact with the movable contact pieces, the static contact pieces are electrically connected to the load contact pieces; and wherein when the static contact pieces are separated from the movable contact pieces, the static contact pieces are electrically disconnected from the load contact pieces.
