Just Bad Switches In DX True 30's???

With all of the talk of these lasers getting dim and/or "dying" not long after receiving them, could it just be a simple case of lousy switches? When I receive mine and if it fails, that's the first thing I'm going to check. I don't think it's worth sending this back to China at my expense so I will open it and bypass the on board switch or simply short it to normally closed, cut the battery leads and temporarily connect a known good switch. If it works this way then we can either mount the laser in a new flashlight case and connect it to the new switch or try and replace the switch with one from a cheapo red . Sound possible guys?
 





MORE than possible ! If you disassemble it, take a switch from a CD or DVD rom or burner deive - the eject button works PERFECT for these pen lasers....just a simple replacement, and you are good to go !
 
Hi Photongeek, Have you tried getting it apart yet? I only ask as I have destroyed 2 to get the modules out (they were dead anyway).
I know senKat and others advocate the wood block method but I pulled and twisted until I was red in the face with no success :-[.

I wish you luck with it. ;)

Its not bad switches, ive been keeping mine on the back of my LCD (nice and warm) and it gives me full output
 
The switch on my DW .1W acts like a Pot. sometimes; the harder I press the brighter the beam.

Anyway those switchs can be desoldered and replaced once the tube is heated and torqued off.

Cool ;D

Guess that's a sure sign :)
I'm not convinced that the switches are the cause of the majority of problems with these lasers, but it's a fault fairly easy to diagnose.
 
ya the switch on my DX 30 got jammed once, so i had to rip the laser and solder it closed ;D ;D anyway i have a nice module now.
