ABSTRACT:
A flashlight has front and rear interconnected housing portions which define an interior waterproof chamber. The waterproof chamber carries an illumination source, an electronic drive for the illumination source and a power source. A switch system includes an electronic switch component for switching the relatively high current required for the electronic drive while a mechanical switch (e.g. a magnetic reed switch) activates the electronic switch component, therefore maintaining integrity of the waterproof seal about the chamber. A commutator assembly is provided to maintain electrical contact between the switch and other components. The power supply may be in the form of a plurality of battery stacks batteries aligned in the housing in a manner to provide a compact unit, while electrical components may be mounted to circuit boards positioned transversely to the length of the flashlight.
