The flashlight of the present invention is comprised generally of a flashlight chassis which houses energy cells, a flashlight head which houses a beam adjustment assembly, and an endcap which houses a switch assembly. The beam adjustment assembly and the switch assembly utilize printed circuit boards to support the lamp bulb and switch, respectively. The beam adjustment assembly mounts inside the flashlight head and can only be accessed and adjusted by removing the outer lens retaining ring that secures the assembly within the head. Once accessed, the bulb support of the assembly can be rotated relative to the reflector of the assembly to adjust the light focal length of the flashlight. The adjustment assembly is also provided with a shock absorber that supports the light bulb. In one embodiment, the endcap is provided with a threads to permit the flashlight to be axially attached to an expandable baton. This embodiment also incorporates a side mounted switch to enhance manipulation and use of the combination flashlight/expandable baton device. In another embodiment, the endcap has an end-mounted switch to permit full extension of the flashlight. In each embodiment, a multi-function, low noise, push-button switch is utilized. The switch mounts on the printed circuit board, and is provided with primary and secondary circuits to guard against switch failure. The switch is protected by a cover integrally formed of an o-ring.
