McE2S for C/M bodies - DIY guide included

EDIT: Since more and more folks are discovering this thread and have questions as to what the Shoope sells and how to put it together, I am re-writing this top post with detail instructions and reusing the photos that I posted later on this thread

To start, let make sure that we use the same terminology. The stock complete, OEM switch on the left is the standard press-to-activate Surefire switch. This is what we are going to call through this DIY the "host". The assembled switch on the right side is what you buy from the Shoope and is what is going to replace the guts of the standard Surefire switch:
IMG_0363.JPG


Again, just to be extra clear, this is what you are buying from the Shoope:
IMG_0360.JPG

IMG_0362.JPG


So we basically have to remove the OEM guts of the OEM host:
1) Remove the spring:
IMG_0364.JPG


2) Pull out the core. Just grab very firmly and pull out with force:
IMG_0365.JPG

IMG_0366.JPG


3) We then remove the retaining ring. This simply unscrews out counter-clockwise. Some folks have reported that they have to heat up the part a little for this to start moving:
IMG_0369.JPG

IMG_0370.JPG


Once you are done, this is what it looks like (new guts on top)
IMG_0371.JPG


4) Now you must enlarge the hole in the retaining ring. Just make it large enough that the new switch guts goes in but small enough that the o-ring can keep the guts from falling out:
IMG_0372.JPG

IMG_0373.JPG


This is how the new parts will go back into the host:
IMG_0374.JPG

IMG_0375.JPG

IMG_0376.JPG


5) Put the outer rubber button back inside the host, screw the "modified" retaining ring back into the host, and finally press in the new guts into the enlarged hole in the retaining ring (if done properly, once "in" it should not fall out by gravity alone):
IMG_0377.JPG


Here is what it looks like when you are done:
IMG_0378.JPG


You should end up with some useless parts as shown here:
IMG_0379.JPG


6) Pat yourself in the back for a job well done

7) Screw the new two-level "C" switch into your favorite LED-driven "C" or "M" host and have fun :D

****************************************************************
Don,

I saw in some older tread that you had made a small adapter ring out of aluminum that would allow your McE2S for "E" bodies to be fitted to "C" and "M" bodies switches. I respect that fact that there might not be enough business to justify making the adapter, but can you please share with me the dimensions of such ring so that I can at least make one for myself? Maybe others here would try to make their own as well /ubbthreads/images/graemlins/grin.gif

Thanks in advance,
Will
(who would love to have one of these on my current KL6 and future KL5!)

EDIT: Look towards the bottom of the tread for an evaluation I just posted of a prototype two-level switch for "C" bodies provided by no other than Don himself /ubbthreads/images/graemlins/happy14.gif

Re: McE2S (two stage switch) for C/M bodies?

Will,
I have been giving this more thought and believe I have a simplier solution than that I have previously shown. I need some new parts to confirm and I ordered them but either ordered the wrong size or was shipped the wrong size! /ubbthreads/images/graemlins/icon15.gif I am still doing some investigation. Provided I don't run into any conflict in IP or previous agreements, I will either provide a solution or at the very least some viable suggestions.

I hope you have a classic size LOTC switch for host?!?

Yes, I do. I am ready /ubbthreads/images/graemlins/grin.gif

Thanks to the 3W BugOutGear module, I suspect that this "new" McC2S (replaced the E with C !!!) would be a great hit with the several hundred folks who have ordered these little neat modules, let alone every KL5 and KL6 owner out there.

Thanks to your McE2S I have come to realize that you "don't" need full power; not all of the time. Yes, high power is great, but a simple, elegant switch like the McE2S makes my KL4 head incredibly versatile. Every single person I show my KL4/McE2S is like "darn! - that IS a nice little light!".

Yes, I also have the U2, which is the high water mark for a simple, reliable, adjustable light, but for most folks two levels is all you really "need" /ubbthreads/images/graemlins/wink.gif

Thanks,
Will

Re: McE2S (two stage switch) for C/M bodies?

Hi Will,
Sorry it took so long to get back to this! /ubbthreads/images/graemlins/blush.gif

Anyway, I realized that it was posible for a larger O-ring to be used on the main body of the 2S module for centering and isolation in the battery tube. This meant that a simple machined disk could be soldered to the PCB to extend its diameter. Actually a larger diameter PCB could be made at a lower cost.

classic-asemblies.jpg


I suppose we should see if Wayne would be interested in the project. /ubbthreads/images/graemlins/smile.gif He could sell the larger PCB and O-ring as a modder's kit for the "Classic" .

The newer style LOTC's have a rivet that connects the main body to a plastic button which is on the other side of the jam nut. To take this apart, you grab the main body with some needle nose pliers after removing the spring and just pull it out of the cap:

clasic-removal.jpg


You then need to remove the jam nut to get the plastic button out and the nut needs to have its hole opened up to 3/8" diameter (drill or rattail file or dremel):

classic-nut-detail.jpg


The older style LOTC's can also be modified but you may have varying levels of success in removing the original components.

I tried one of these versions on a KL6 (30 ohms) and it works great. I also tried one in a black 6P that is hosting a KL3 and it also works real nice (60 ohms chosen).

No worries dude - this is great news /ubbthreads/images/graemlins/happy14.gif

So all we need now is to convince Wayne? /ubbthreads/images/graemlins/wink.gif

Do you by any chance have the dimensions handy for the new overal diameter of the PWB and the new O-ring size?

Re: McE2S (two stage switch) for C/M bodies?

The New PCB or an extension disk should be about .800" in diameter. The O-ring I used is a dash 203.

If you want to E-mail me your mailing address, I'll send you an O-ring and one of these modified PCB's with disk. Let me know what resistor total you want too. (First one for you is free and then bend over!!! /ubbthreads/images/graemlins/nana.gif )

New prototype switch arrived !!!

Don,

First, thanks again for trusting me with your prototype. I hope that my evaluation/photos is enough "reward" in the short term. Longer term, I am ready to buy at least 3 additional units right away - PayPal ready!

So lets get started. Here is the prototype switch unit that I got from Don to test/evaluate next to my L6:
IMG_0359.JPG


A closer view:
IMG_0360.JPG

IMG_0361.JPG

IMG_0362.JPG

IMG_0363.JPG


Here I start the dissasembly of the host switch per the high-level directions from Don:
IMG_0364.JPG

IMG_0365.JPG

IMG_0366.JPG

IMG_0367.JPG

IMG_0368.JPG

IMG_0369.JPG

IMG_0370.JPG


Here is a good image of the inner workings of the factory switch next to the prototype:
IMG_0371.JPG


Per Don's instructions, we need to make this whole larger. As the material is rather soft, I decided against the dremel tool this time and used a rat file:
IMG_0372.JPG


In no time, the whole is ready:
EDIT: Make the whole just big enough for the top to slide with resistance from the o-ring as this is what will keep the module from falling out.
IMG_0373.JPG


And here I put it back together:
IMG_0374.JPG

IMG_0375.JPG

IMG_0376.JPG

IMG_0377.JPG

IMG_0378.JPG


Of course, now I have some useless parts laying around /ubbthreads/images/graemlins/icon15.gif
IMG_0379.JPG


Lets start with the testing /ubbthreads/images/graemlins/smile.gif. Please note that Don sent me this particular prototype with a 30Ohm resistor as I requested for the "LOW". All photos taken with a Canon Rebel XT with the kit lens set to 18mm, and manual exposure of 1 sec @ F5.6 with automatic white balance. Wall is about 15 feet from the camera and my daughter's toys are about 1 foot away from the wall.

Here is a G2 with a BOG 3W module modded by me with a UX1L LuxIII running with the stock driver on two Rechargable CR123 cells. First on LOW then on HIGH:
IMG_0395.JPG

IMG_0396.JPG


Here is my L6 (modded for 1A) on LOW and then HIGH
IMG_0399.JPG

IMG_0400.JPG


And finaly, here is my M4 with a TurboHead and an LED module built by me using a LuxV WX1T with a Downboy @ 1A, LOW then HIGH:
IMG_0401.JPG

IMG_0402.JPG


For comparison only, here is my U2 on level 1 and then on level 6 (using the stock switch - not using the prototype):
IMG_0397.JPG

IMG_0398.JPG


Comments: The prototype worked great and it was very easy to install. It worked with 3 different drive circuits so I would expect that like the original McE2S this one will have wide use on any/all "C" bodies that drive an LED.

The only things I would like as improvements are minor, but worth mentioning:
- there is nothing holding the "module" inside the host tailcap. I don't know how to "fix" this, but I would gladly buy at least 3 more - I like it that much!
- The stock spring presure was a little bit too high for my taste, but easily fixed. I have done so as well on my EDC that uses a McE2S switch (it is literaly a hair trigger which is fine since I have the flat top with its recessed button).
- It took more than a full turn to go from high to low, but again, this is something I also modified on my McE2S (its about a 1/2 turn on mine).
- The modified tailcap did not go as deep into the body compared to the stock switch before it would turn on. You can see the larger-than-normal gap in the photo above of the L6 with the extra parts right below it - note the lanyard and the gap. The o-rings were still engaged, so no worries here as nothing is compromised.

So how is it? This thing rocks - I want (scratch that), I NEED 3 more of these /ubbthreads/images/graemlins/buttrock.gif

All we need now is to convince Don (and Wayne?) to get this into production /ubbthreads/images/graemlins/smile.gif

Thanks again Don for your trust - you are awesome /ubbthreads/images/graemlins/bowdown.gif

Re: New prototype switch arrived !!!

Will,
Great work up here! Now to comment on the improvements suggested.
1) If you opened the bore in the jam nut to 3/8" ID, the O-ring on the button should retain the module in the tailcap and provide pseudo lock out as well. /ubbthreads/images/graemlins/icon3.gif
2) the main body can be modified into a hair triger as you have suggested and you can use the original SF spring instead of the one with the McE2S module as it may be softer in some iterations.
3) If Wayne will do the larger diameter PCB (I sent him the dwg but he has to turn it into a real file that can be used), this will result in a module that is not as tall as this proto so the cap will come down further on the battery tube before the switch engages.

BTW, if you have a Pelican M6-LED, you will find that this switch should work on it as well. /ubbthreads/images/graemlins/nana.gif (compresses the spring more but does work)

So bottom line, bug Wayne! I did my part! /ubbthreads/images/graemlins/grinser2.gif /ubbthreads/images/graemlins/crackup.gif

I have some PD's to build if he would send me the converters! /ubbthreads/images/graemlins/str.gif

Re: New prototype switch arrived !!!

Just did the layout. I need to find a place that can do this thickness board.

Re: New prototype switch arrived !!!

Don,

1 - I made the hole a tiny bit past the size of the o-ring on top - that is why it falls off. The hole needs to be tigher around the O-ring - good to know. I edited the post above to note than for future modders /ubbthreads/images/graemlins/wink.gif

2&3 - Excellent!

Looks like the road is paved for this to become a reality. I am more than happy to provide not only the photos listed but any additional testing/photos that either you or Wayne need to make this a go - just ask /ubbthreads/images/graemlins/smile.gif

Re: New prototype switch arrived !!!

Guys -

Great work!

I presently have alum stock in the lathe for adapting this concept to the G2. The G2 needs a different top button to work with the existing tailcap body and rubber switch cover.

I have already turned out the brass adapter ring to adapt the resistor board to the "classic" configuration, but need to finish the top button piece to make it work on the G2 (non-lockout tailcap).

I *think* I can make this work, but will have to try it out to verify for certain. Too bad the new LOTC's aren't quite available as replacements yet /ubbthreads/images/graemlins/frown.gif

Again, nice work guys!

John
