ABSTRACT:
A clamp for battery jumper cables includes a pair of pivoted terminal gripping members with a switch and linkage arrangement connected between a conductive jaw and the conductive jumper cable to facilitate electrical connection and disconnection of the jaw and jumper cable in a controlled, spark-free manner. The linkage includes first and second lever sections pivotally connected to one of the handle sections of the terminal clamp. A first lever is operated as the clamp is grasped in the user's hand. This lever causes the over-center linkage to shift to a first over-center position, opening the switch and breaking electrical contact between the clamp and jumper cable before the jaws are forcibly opened. The over-center linkage serves to hold the switch in an open, nonconductive state even though the clamp handles are released to secure the jaws against the terminal. A second lever must be consciously pressed before the switch is allowed to move to a closed condition and electrically connect the clamp and jumper cable. The second lever is pressed to shift the over-center mechanism back over-center bringing first and second contact surfaces of the switch together in flush conductive engagement. Subsequent grasping of the clamp will cause the switch to be opened before the clamp is removed from the terminal.
