A hand-held, focusable beam flashlight has a barrel portion, a head unit, and a socket/switch assembly coupling the head unit to the barrel portion. The barrel portion has only one open end, thus eliminating the need for a tail cap. The socket/switch assembly is mounted on the open end of the barrel and retains one or more power cells therein. The switching mechanism is independent of the force necessary to maintain the power cell in electrical contact with the socket/switch assembly. The head unit is formed to controllably translate axially relative to the socket/switch assembly. The head unit includes means mechanically coupled to the switching mechanism whereby the electrical circuit to the flashlight bulb may be switched off and on as the head unit translates along the socket/switch assembly. The switching mechanism has essentially no slack, and therefore switching occurs with only a small axial movement of the head unit.
