Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
