Battery jumper cables with safety switch
First Claim
1. In a pair of battery jumper cables having a safety switch in one of the cables, the improvement comprising:
- a switch body made from an insulating material and having a cavity;
a switch handle at the top of the switch body and pivotably connected thereto;
a pair of electrodes extending into the cavity and connected to one of the cables;
a plunger rod extending from the top through the switch body and into the cavity; and
an electrical connector located within the cavity and slidably attached to a bottom portion of the plunger rod, wherein depression of the switch handle pushes the plunger rod downwardly causing the electrical connector to contact the electrodes thereby closing the switch, and wherein partial release of the switch handle does not break the electrical contact between the electrical connector and the electrodes but full release does.

Abstract
A pair of battery jumper cables are provided with a safety switch to eliminate serious injuries that can occur during the jumping of a dead or weakened battery because gases from the battery are ignited by a spark which results from the connection of a hot lead to a battery terminal. A durable, insulating safety switch is provided in one of the battery cables equi-distant from either end. The switch has a handle which when depressed makes electrical contact between the leads of the battery cable. Additionally, the switch is designed to maintain electrical contact between the battery terminals until the switch handle is completely released.
