A breaker has a first conducting strip and a second conducting strip respectively mounted on a lower end of a shell; a bimetal strip securely provided on a first conducting strip; a second terminal mounted on a tip of the bimetal strip and detachably connected to the first terminal; a button provided on an upper end of the shell; a finger pivotally provided under the curved spring; and a lever with a smooth surface provided between the bimetal strip and the finger wherein an end of the lever is bent to form an angle. Hence, the finger can slide on the smooth surface of the lever so that the button can completely return to an original status. Furthermore, when the angle is small, the finger counter clockwise rotates with a small stored power of the bimetal strip.
