After my Jetbeam BC10 died after about five years of ECD use I went online to buy its replacement to find out that the highly desirable tail cap switch is no longer found on nearly as many small light models as it used to be.
To me it's the perfect location for a light switch on a pocket size flashlight. They seem to have gone back to a twist type switch or a small button on the side of the body on most of their more recent models.
Both JetBeam and Fenix seem to be going this route.
Any known reason why the tail cap switches are going away?
High failure rate maybe?
