1. An automotive battery terminal clamp for a battery jumper cable, comprising:

  • a pair of terminal gripping members each including a jaw section and a handle section, at least one of the jaw sections being electrically conductive;

    a pivot pin joining the gripping members together for pivotal movement relative to one another about an axis between the jaw and handle sections thereof;

    biasing means on the gripping members for normally urging the handle sections apart and the jaw sections together about the axis so that a hand forcibly gripping the handles against resistance of the biasing means may pivot the handles toward one another and thereby cause corresponding pivotal motion of the jaw sections apart from one another and so that relaxing of the hand grip will allow the jaw sections to close responsive to the biasing means;

    a switch mounted to the gripping members and electrically connected to the conductive jaw section and adapted for connection to the jumper cable, for selectively opening and closing to make and break electrical contact between the conductive jaw section and jumper cable; and

    an actuator means on the pair of gripping members and connected to the switch for (a) opening the switch to break electrical contact between the conductive jaw section and cable responsive to said gripping, (b) holding the switch open following release of the handle sections, and for (c) selective operation to close the switch.
