Kroll Tailcap Switch - built to original specs by original mfr. Original thread pitch, length works with Minimag etc.
Exactly same specs before. Improved spring action.
Note from mfr:
Judco Manufacturing’s End Cap Switch, aka KROLL SWITCH, has been used by flashlight enthusiasts for years because it fits many popular lights.
Our J1052 End Cap switch series has an innovative feature, which allows the light to turn on momentarily without having to click it on and off again. It comes in handy when a quick look is all that’s needed.
Customer satisfaction is our goal and we are continually striving to improve our switch design. The KROLL SWITCH (J1052 End Cap Switch) now provides better contact between the metal cup and the battery spring. The change increased the spring pressure, which provided better conductivity and lower resistance.
