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.
