If they don't work for you, you should send them to me so that I can use them with my MiniMag LEDs. (actually I'll have to go buy a couple more, 'cause I'm already using Krolls on all of my MiniMag LEDs
)
The reason that they don't work is because a Kroll switch just has that flimsy spring on the side to make contact with the body of the light of the light. Also the spring for the negative battery contact isn't long enough (remove the one from the MiniMagLED tailcap and use it to replace the one on the Kroll switch.) On the MiniMag LEDs (both) that area of the body is anodized and prevents the Kroll switch from completing the circuit with the body of the light. The challenge to you would be how you choose to complete that circuit; as there is no one correct way (other than redesigning and remanufacturing the Kroll switch.) Amongst the alternatives that you have are removing the anodizing from the lower 3/8-1/2" of the interior of the light, cut off the portion of the light that is anodized, fit the Kroll switch with an extended contact area to complete the circuit.
If you just need a mickey-mouse fix to see how it works with the Kroll switch, you can jamb a piece of aluminum foil in between the spring and the plastic on the side of the switch, making sure that it extends to the top of the switch (but not touching the battery spring.

I tried both of the Krolls, on the MagLED, didn't work. Aargh. Now what can I use these for?
