1. An electrical receptacle, comprising:
a live terminal having a first contact attached to a bimetallic dish,
a feed terminal having a second contact, and
a reset button having a columnar body with a cavity at its base and a button surface at its top and an extension portion located on one side of the columnar body, the extension portion having an arm on its distal end, the reset button also having an internal spring located in the cavity,
wherein,
in a normal reset state, the bimetallic dish bends inward so that the first and second contacts touch and the reset button is in an untripped position and the arm is prevented from moving upwards by the first contact, and
in a tripped state, the bimetallic dish bends outward enabling the internal spring to push upward the arm of the reset button between the first and second contacts so that the reset button is in a tripped position wherein the arm abuts the second contact, the presence of the arm between the first and second contacts preventing the first contact from touching the second contact even if the bimetallic dish bends inward again,
and wherein manual depression of the button surface of the reset button returns the reset button to its untripped position.
