ABSTRACT:
An electrical breaker includes a casing with a pushbutton pivotally connected to the top thereof, an alloy plate extending from one of two inside walls of the casing and connected to a first prong extending from the casing, a push member and an L-shaped member pivotally connected to the first end of the pushbutton, a biasing member biasing the push member to let the protrusion of the push member press against the other inside wall which has a recess defined therein. The distal end of the alloy plate is pushed by the push member to contact the second prong when the first end of the pushbutton is pushed, and the distal end of the alloy plate is disengaged from the second prong by the horizontal portion of the L-shaped member when an overload current passes through the alloy plate which curves to push the first end of the pushbutton upwardly.
