Abstract: A disposable flashlight includes a battery and bulb within a casing, a conductive clip engaging the battery and extending through an elongated peripheral slot in the casing, and a conductive member engaging a terminal of the light and extending into proximity with the end of the clip so that the end of the clip can be pushed through a contact opening in the casing into electrical contact with the conductive member to turn the light on. The peripheral slot extends a sufficient distance along the circumference of the casing so that the clip can be rotated within the slot to an "off" position in which its end no longer overlies the contact opening within the casing. In that position, the light cannot be activated when pressure is applied to the clip.
