Abstract
The present invention relates to a flashlight assembly having a rotatable head which acts as a switch mechanism for turning the light on or off. The flashlight has an elongated metal housing, and the rotatable head is also made of metal. A spacer member made of an electrical insulating material is securely attached to the head member. The spacer member threadedly engages threads formed on the housing. Thus, there is normally no electrical continuity between the metal head member and the metal housing. However, when the head member is rotated in a tightening direction, a flat annular face on the head member comes into mating engagement with a similar face on the housing, thus establishing electrical continuity between those two members and completing the internal electrical circuit of the flashlight.
