The present invention discloses an inline switch mechanism that operates in a reverse direction, making electrical contact as the flashlight head is unscrewed. The switch has an outer housing, an inner contact tube, a plunger, a contact spring, an insulator disk and a secondary spring. All of the components are electrically conductive with the exception of the insulator disk and outer housing. In the off position, the plunger floats, centered in the contact tube, with a contact end in electrical communication with the battery. A contact spring is disposed around and in electrical communication with the plunger. The insulator disk is on the back of the plunger supporting it and isolating it from the contact tube and is disposed between the plunger and the secondary spring. The secondary spring at one end exerts pressure on the insulating disk and thereby the plunger maintaining contact on the battery and at the other end contacts one side of the LED bulbs and is in electrical communication with the contact tube.
