Abstract:
An underwater flashlight (10) has an adjustable focusing beam and a waterproof battery pack (12) which can be removably changed underwater. The flashlight includes a watertight housing (11) having a slidably mounted lamp (18) therein slidable by an external sliding focus member (14) having a permanent magnet (35 & 36) mounted therein. The permanent magnet (35 & 36) moves an internal sliding focusing member (38) also having a magnet (37) therein coacting with the external magnet (35 & 36). The slidable inside focusing member (38) is connected by a link (41) to the lamp (18) for moving the lamp into and out of a reflector (16) when focusing the lamp. An on/off switch (27) is attached to the slidable outside focusing member (14) and has a magnet (26) mounted therein for actuating a pickup coil (32) attached to the slidable inside focusing member (38). The flashlight includes a waterproof attachable battery pack (12) which has a magnetic switch (52) therein actuated by a magnet (54) in the watertight housing (11) of the flashlight so that the batteries (47 & 50) do not provide an electrical connection until the contacts are brought together.
