ABSTRACT:
A flashlight having a reinforced tubular plastic casing including a battery compartment and a bulb compartment separated by a transverse wall integrally molded with the casing. A bulb is retained in a socket integrally molded with the wall by a bushing which may be quickly connected and disconnected from the socket, the bulb and the bushing being resiliently axially moveable with respect to the socket and the transverse wall to prevent breakage of the bulb due to shock or impact. A novel reflector is axially moveable with respect to the bulb to afford adjustable focussing of the light emitted from the bulb. The reflective surface of the reflector combines a facetted parabolic surface on the outer portion of the reflector with a smooth spherical surface at the base of the reflector to optimize the amount of light collected from the light bulb and focused in the beam. A novel three-position switch assembly includes a one piece plastic actuator having an integrally molded pivotable pushbutton lever which may be actuated to flash the lamp on and off. The actuator is quickly and easily snapped into place in a switch housing to facilitate assembly.
