Abstract:
1. A lever switch for safe breaking of a circuit of an exercise apparatus wherein two conductive copper pieces are spaced apart and stably received within a housing by means of elastic pieces, and wherein a rotatable cylinder with two journals is positioned in the area of the contact portion of the conductive copper pieces within the housing, and wherein the rotatable cylinder is provided with a contact polygon at one side thereof such that the contact portion of the rotatable cylinder is constantly clamped at the top and bottom ends of the contact polygon, and wherein a conductive wire is embedded within the contact polygon, whereby an insertion lever may fit into a body portion of the rotatable cylinder for in-place-moving the rotatable cylinder such that the contact polygon is turned to be detached from the conductive wire or to be in contact with the contact portion of the conductive copper pieces for safe breaking and making of a circuit.
