… Why?

One reason is that a broken sk68 switch is non-servicable. And how to solve that is a matter of styling Smile

Until you posted this I actually assumed every part of these clones could be replaced!

The parts inside the sk68 switch are tightly press-fit, not made to disassemble, if you manage to open it usually something breaks, and even if you manage to not break anything it will not re-assemble well again.

I am too much of a noob to know this – but maybe someone else does:
Which light was “the original” SK68, if there was one in existence? Was it better or as bad as the clones? Better to mod / worse – and can the “real deal” be purchased somewhere?

SK68 switches are replaceable. You can buy the switch modules, including the switch and a fresh plastic retaining ring and washer for them. I have a bag of replacements at home.

Kaidomain sells them. Unfortunately the link has an underscore in it and if I try cutting and pasting only half the link appears. But it’s on page 2 of their reverse clicky switch section.

That said. Not everyone wants to spend $2.48 on spare parts for a $5 flashlight, so OP’s solution works.

There was never an original SK68.

Some guy bought a surplus batch of automotive shock absorber cases and miscellaneous flashlight part and stuck them all together.

Nice work! What thread pitch did you use for the lower wood section? Big Smile

The Nitecore Extreme is what the SK68 body is a knock-off of, the Nitecore however is a reflector based light so not a true clone.

Oooh, they DO have replacement switches?! And free shipping. Well alrighty I just bought some. Assuming I can dig out the original switch without jacking up the silicone cover. At 5 switches for $2.50 it makes sense to me replace a switch, ‘long as something else doesn’t burn out immediately.

In my searches and video watching, it’s been suggested that Sipik is the original. But I don’t know. And whether or not it’s any better I don’t know, either.

The bolt is #10-24. I think 1/4-20 could be used if hardwood ply was also used. Smaller bolts with finer threads would probably not be a good idea due to the ease of denting the battery with even #10 bolts. But I suppose it doesn’t matter if switches are available. Then again, it’s fun to exercise your inner MacGyver!

That makes more sense than Sipik. I think those were sold on DealXtreme according to light searches, so unlikely to be original anything. But if they brought the zoom, then that’s something. I don’t think I could give up zoom.

It just occurs to me that you’re probably wondering about the thread that screws the wood onto the body of the light. I just decided to make a square of wood, then bevel each corner. I increased the bevel depth until the size of the wood was small enough for the flashlight threads, whatever they are, to “bite.” Then I put the wood in the vise and carefully forced the body of the light onto the square.

My recollection is Kaidomain also has compatible rubber boot covers. If you’re ordering switches from them might want to get some spare boots while you’re at it.

Ehhh, I got my sister to buy four of them 3+ years back, just to have. They were about $20 shipped from China and while I was back visiting, one wouldn’t consistently fire up, since the tube had an alkaleak leak. I tried sanding things down, but no dice.

I pitched it in the trashcan.

You actually spent $5 on this light? Woof!!! I think i got 3 for $10

That being said, hey robin. Does the new switch prevent it from coming on in your pocket?

never fear shadows…it means a light shines nearby

Maybe not, but it gives new meaning to someone “having a woody”…

Got the switches Lightbringer linked to that Firelight2 was talking about.

To press the old switch out and save the silicone, I used a 3/8 bit mounted backwards in the drill press with the tailcap pointing into an appropriately sized hole.

The new switch wasn’t near tight enough, so I used some thick aluminum foil I cut from a store-bought pie crust to shim. Seems about right. I wouldn’t mind if it were tighter, but I don’t know how to make it tighter and get the foil to behave. As it is it works, so I’ll have to be satisfied with it until it doesn’t work. Then maybe I’ll buy a real flashlight.

Oh, I did also get the cheap SK68s from ebay. They are very similar, but the battery cavity is too large and the emitter not nearly as bright. Doesn’t say anything about 3.7v, either. There are definitely different levels of quality of these things.

The wood switch didn’t turn on in my pocket, but I didn’t have the light in my pocket much. If I go on a walk/run, the light is out and ready, or I may as well leave it at home. Dogs come out of nowhere, snakes appear out of nowhere, not to mention the harmless things like ‘possums and armadillos I’m constantly tripping over.
