Abstract:
1. A control system for automatically switching power between two separate light sources integrated with a welding shield pivotally mounted to an adjustable headband comprising: at least one magnetic positional switch attached to the headband having electrical communication with at least one battery and the light sources; and two magnetic positional sensors strategically mounted on the interior surface of the welding shield along a defined arcurate path of rotation of the shield about the headband; wherein at the lowermost rotational position of the welding shield relative to the headband, one of the two magnetic positional sensors is aligned with the magnetic positional switch causing current to flow to one of the two light sources and wherein at the uppermost rotational position of the shield relative to the headband the other of the two magnetic positional sensors is aligned over the magnetic positional switch causing current to flow to the other of the two light sources.
