Modding a Judco Switch

I'm not sure why this cant be done unless I'm missing something. In the first picture if the top terminal strip/contact is rotated 180 degrees so that it could be used as a normal switch in a tailcap. The side of the plastic, can it be cut out to accommodate the strip coming out the opposite side?

Notice the pins in the left side of the picture. They are close together where the contacts are. Notice the pins on the right side of the picture. The pins are farther apart. The left side shows the contacts are cut out to fit within the pins. The other ends do not. If one contact faced the other way, it would not be aligned, because the pins are farther apart and the contact would not be held in place well. It would not be kept from shifting sideways and it would not make correct contact with the center horn.

EDIT: You could make new copper contacts and that should work properly.

Would you like one to try it out on?

MRsDNF, would you like me to make you a modified Judco switch that will work like a Chinese Tail Clicky, complete with the reversed contact and a spring base?

I just figured out how to do it.Wink

Ok. Thanks OL.

Who you talking about Willis, Sorry Rufusbduck?

I will post the mod here and send you the result.

I thought you might use a switch like that as a tail clicky in the copper tube.

I am using one in the copper tube as a tail clicky, just not with a spring, but direct wired.

Doh! No battery, no spring.

I think you did great on modifying it. Now I believe you are more proud of your Judco Pushbutton switch.

I think this conversation is getting like one of those phone calls with a 3 second delay. Everyone talks on top of each other and no one has a clue whats being said.

Thanks OL I would love you to make the said switch with idiot instructions just for me. Can you please include a link to the switch to save me searching for the link you sent me last time. Cheers, confused idiot (me).

Hey O-L, I just want to say that you’re also doing a great job with the photography. Really helps folks like myself to be able to clearly see what is being described. Like a roadmap to DIY, :slight_smile:

Thanks for going to the extra trouble with photographic documentation, it’s really appreciated!

Originally a 10 amp Judco switch.

I made two new contact strips out of copper sheet. They still need tro be trimmed a little.

dnf2

Bottom contact for a spring

dnf3

Side contact

dnf4

Epoxy to seal the end

Tested with a meter. Works...

Will that work for you MRsDNF?

Thank you very much sir. Your copper for the tabs, would that be about 20 thou in thickness?

Stock was .014". I only had .012"

Where’s the best place to buy these switches?

Digikey but I wish their site were easier to navigate. You want the Judco 10A push button on/off or off/on(reverse and forward clicky). If you click on the part number you will get a page that has links for button covers as well. Maybe OL has a direct link. I use a variety of different Judco switches.

Just use the colums of information to look for the amperage and style you want.

I use this one most of the time: Judco Part# 40-4520-00

This is a great thread. I was just starting to mod a tail cap to take a Judco switch when I remembered O-L did thread on modding a Judco switch. Thanks to this contribution, I will take a different and better approach to the mod. Thank you O-L.

Bookmarked!
