Abstract
A switch for a portable light source such as a flashlight which has a housing for carrying one or more batteries and for supporting a lamp bulb. The switch includes a switch body securable to the housing and an actuator that is axially moveable relative to the switch body for electrically coupling and uncoupling an electrode of the batteries to one of the terminals of the lamp bulb to switch the lamp bulb on and off. The actuator is also rotatably moveable relative to the switch body to prevent axial movement of the actuator and thereby lock the flashlight in the on state.
