surefire king mod help!

[keithmoore1227]

i have a surefire king mod and the button on the bottom is getting hot. not sure why this is. can any of you help me with this problem that i am having

What sort of carto, atty are you using?
What resistance, ohms?
Is the battery also getting hot? (would be a very bad thing, showing an increase in internal resistance)
Have you cleaned the contacts on the mod?

Battery is not hot and I am using a Igo w with a .5 ohms

High resistance connection at the switch, probably where the spring contacts the bottom cap.

As to a fix, without owning one, I couldn't tell you how to proceed.
