Abstract

Provided is a device mounted contactor and a method of reducing continuous charge distribution, especially in a vehicle. The contactor includes a housing, and a plurality of power terminals. The device may further include a conductance shield and support structure extending from the housing. Situated at least partially in the housing is a switch, which is capable of electrically coupling at least two of the plurality of power terminals. One or more electrically insulative covers may be provided. The contactor may also provide a fused accessory terminal, which is electrically coupled to one of the power terminals through a fuse. A method according to the present invention reduces continuous electrical charge distribution in an electrical circuit by mechanically attaching a first contactor power terminal to a battery terminal and electrically coupling a second contactor power terminal to a circuit, which may include a vehicle starter.

Claims

1. A system comprising:

a battery including a plurality of electrically conductive battery terminals; and

,

a device comprising;

a housing having an internal cavity,

a switch at least partially contained in said internal cavity,

a first power terminal extending from said internal cavity through said housing,
