Abstract

A slide focus flashlight has a container with an aperture therein, a lamp disposed within the container, a reflector disposed within the container, and an actuator disposed in the opening of the container for sliding therein and having a first angled surface. A conductive shaft is disposed within the container, and a slide interface is coupled to the conductive shaft. The slide interface has a second angled surface for sliding against the first angled surface of the actuator. A power switch is provided for selectively energizing the lamp. The slide interface, actuator and power switch allow for single-handed focusing and energizing of the flashlight.
