Abstract
A portable illumination system comprising distal and proximal members rotatably coupled to one another. The rotatable coupling between the members includes resistive rotational feedback across a plurality of independent rotational regions between the members. A rotational switching mechanism is configured to switch between an activated state and a deactivated state. The activated state includes an electrical coupling between an electrical power source and an electro-optical output device across a plurality of independent rotational regions between the members. The plurality of independent rotational regions of the activated state corresponds to a linear or lengthwise alignment between the distal activated indicator and the activated proximal indicator. The plurality of independent rotational regions of the resistive rotational feedback may be coordinated with the plurality of independent rotational regions of the activated state. A second alternative embodiment of the portable illumination system includes a rotational switching mechanism with an electrical switching system and an operationally independent resistance system.
