ABSTRACT:
A rugged, heavy duty flashlight which is hermetically sealed to prevent intrusion of moisture and dirt. A manually operable electric switch is provided having a rotary contact to complete the battery circuit to the bulb. When the switch is actuated the rotary contact is moved axially to engage stationary contacts and is then rotated to wipe against such stationary contacts to clean the contact surfaces. The flashlight is readily adjustable to change from a narrow concentrated light beam to a broad scattered beam.
