flashlight is not in a battery charging mode the tailcap may be used as an alternate flashlight switch to turn the flashlight on or off while maintaining a certain predetermined focus for the light beam as shown in greater detail in fig1 the tailcap switch assembly 94 is in the 34 charge 34 position for charging and in the 34 off 34 position for normal flashlight operation in the tailcap position shown with the head of the flashlight rotated to be in the 34 on 34 position as described previously the circuit is broken between switch contact 71 and ground contact 72 at the region of scallop 74 in this position the forward ends of the switch contact 71 extend up through the scallop holes 74 cut in the ground contact 72 but do not touch any part of ground contact 72 the scallops are also shown in fig1 thus the circuit from the barrel to ground contact 72 is broken at 74 as shown the remainder of the circuit after the break is from switch contact 71 to battery spring 73 to the electrode of the rearmost battery and thereafter to and through the head assembly as previously described when the switch knob 67 is rotated.
