E2 - Convenient "Rotary Switch"

There is a way to use the E2 in normal "flashlight position", along with a convenient switch, as an alternative to "tac" position. First, tighten the tailpiece until it lights; then unscrew the bezel just enough for the light to go out. Then just hold it like a regular flashlight and use the belt clip as a rotary thumb switch; it's easy and requires only a slight motion. If you try this in reverse by tightening the bezel, securing the loosened tailpiece with your fourth or 5th finger, and rotating the E2's body, it can be made to work, but it's much less efficient than the first way
