TK40 Help

[maddog]

Hey All,

i'm having problems with my TK40. the switch is giving me fits. to turn it on or off sometimes i have to double click it. this in turn sometimes changes my power settings if it doesn't turn it off.

is there a to convert or mod the switch to just be a on/off switch that is set to the turbo setting?

thanks,
brandt

I'm no expert, but the general troubleshooting for switches is clean and lube threads;contacts etc. And then in this case adjust the internal depth of the switch itself. If You unscrew the tailcap you will see 2 dimples, a pair of needlenose can be used to adjust the depth. Good luck

My first TK40 had the same problem - missing clicks. I contacted the dealer and they replaced the entire light with a new one - no problems since.

I read somewhere once that all the clickies you see in flashlights nowadays were not meant for this type of use. This is because the current flowing through them are just too much for them to function reliably; on top of this they are just complicated so the chances of something going wrong are pretty high.

yer, i kinda agree with this. is there any way i can by pass this clicky switch or modify the current switch to a regular on/off switch that is set to high?

I don't know how to modify the switch as you want it, but the switch on my TK40 was driving me nuts over the past week or two. I had to press it *extremely* hard to get the light to turn on/off or change modes. To fix it, I just opened the switch with a small needle nose pliers (as described before,) disassembled the switch, and squirted some electrical contact cleaner inside the actual switch assembly on the PC board.

It works just like new now with nice, soft presses on the switch.

Before making all the modifications you described, you might want to try cleaning your switch just for starters.

sounds good and i might try that. but as i only use it on high i thinking about just trying to get rid of the bling and just go for the on/off (no more problems with that switch ... )

In the TK40, the switch passes a very tiny current (less than a milliamp), which signals the controller to turn the light on.
