The present subject matter relates to a tail cap for portable lighting device such as a flashlight. The tail cap includes a locking mechanism which secures the tail cap on the flashlight as well as enables or disables the switch that activates, or deactivates the flashlight and/or its various lighting modes. The tail cap with the present multi-purpose locking mechanism allows the user to rapidly replace the battery, and ensures that the switch and contact pins return to the correct position, after the tail cap is reinserted. The combined use of a magnetic switch and O-ring gasket between the tail cap and main housing ensures complete waterproofing. The ambidextrous switch consisting of either a switch bar or dual push-button switch located on the rear wall of the tail cap allows ambidextrous use, even when the flashlight is mounted on a firearm such as a handgun, where the trigger guard would normally interfere with the operation of a switch mounted on the rear face of the flashlight.

Capuchon arrière pour dispositif d'éclairage portable, tel qu'une lampe torche. Le capuchon arrière comporte un mécanisme de verrouillage permettant de le fixer sur la lampe torche et d'actionner ou de bloquer le commutateur qui allume ou éteint la lampe torche et/ou ses divers modes d'éclairage. Le capuchon arrière doté de ce mécanisme de verrouillage polyvalent permet à un utilisateur de remplacer rapidement une pile et, après sa réinsertion, fait en sorte que le commutateur et les broches de contact reprennent leur position correcte. L'association d'un commutateur magnétique et d'un joint torique entre le capuchon et le boîtier principal assure une étanchéité totale à l'eau. Le commutateur prend la forme d'une tige de commutation ou bien d'un commutateur à bouton-poussoir situé sur la paroi arrière du capuchon arrière permettant son utilisation ambidextre, même si la lampe torche est montée sur une arme à feu, telle qu'un pistolet, dont le pontet gênerait normalement l'actionnement d'un commutateur monté sur la face arrière de la lampe torche.
