Abstract
A lever switch for safe breaking of a circuit of an exercise apparatus includes two conductive copper pieces spaced apart and stably received within a housing by means of elastic pieces. A rotatable cylinder with two journals is positioned in the area of the contact portions of the conductive copper pieces within the housing. Moreover, a rectangular piece is provided at one side of the rotatable cylinder such that the contact portions of the conductive copper pieces are just clampable to the top and bottom ends of the rectangular piece. In addition, the middle portion of the conductive copper pieces is inwardly bent to form corresponding conductive contact surfaces. As a result, an insertion lever may fit into the body of the rotatable cylinder for in-place-moving the rotatable cylinder such that the rectangular piece is turned to bring the conductive contact surfaces of the conductive copper pieces in an electric disconnection or connection state for safe breaking and making of a circuit.
