Vehicular battery charging switch

Abstract

A vehicular battery charging switch comprising a tubular vial having a front end, a rear end, and a small amount of electrically conductive liquid material disposed therein; a coupling mechanism for coupling the vial to a vehicle such that its front end is positioned below its rear end when the vehicle is positioned on a level grade; and a pair of electrical contact pins coupled to and extended within the front end of the vial with one contact pin adapted to be connected to an alternator and the other contact pin adapted to be connected to a voltage regulator that is associated with a battery; whereby when a vehicle is travelling on level-grades and on down-grades, the front end of the vial is held below the rear end thereof such that the conductive liquid material is placed in contact with the contact pins, thereby connecting the alternator with the voltage regulator and allowing charging of the associated battery, and when a vehicle is travelling on up-grades, the front end of the vial is tilted above the rear end thereof such that the conductive liquid material breaks contact with the contact pins, thereby disconnecting the alternator from the voltage regulator and preventing charging of the associated battery.
