Where to score Sigelei #20 switch spring? anywhere? or even upgrade/mod?

[dezyner]

sigelei #20, for what it cost, I dig the mod, hate the switch tho. gotta be a way to upgrade it isn't there? been reading for hours, can't find much on it. Mine's (Edit: Switch Spring) not exactly "symmetrical". The switch connection spring doesn't instill confidence to say the least. Stripping the mod is easy enough. Has anybody actually put a Roller switch in this,... yet...lol. Saw something about using brass tubing, but, seems like that might get wedged in there? As always, thanks in advance. Cheers.

Probably about the best you can do is: #20 Switch Assembly Nevermind, sold out. So your options are to make your own or stumble across something that works.

Are you talking about the spring in the button, or the tight wound copper spring that completes the circuit?

My best idea for a replacement to make it better is to replace the pins with tubes/cylinders of copper or brass, then make a floating switch bit out of a tube cut in half vertically to make the connection. Best way to describe it is if o is a top view of the pins, ) would be the top view of the "floating" switch connector.

So at rest you have: o )--|
When you push the button (The | in this case) it would move the ) over to contact the two posts
Like So: o)--| <-press!

If that makes ANY sense

yep, the circuit spring is the one I want to replace. thank you. makes ALOT of sense. pretty sure I am heading out the door for parts. thanks. sketched it out from what you said, should fix it nicely.

Bam, spot on! Make sure to post either here, in the huge Sigelei thread, or somewhere and maybe shoot me a PM so I can see what you did?

nothing I could find on the shelf would work. what i did was try to fabricate the parts, without specs, or a lathe. so, i wound up turning the "lathe"(dremel) around the part. not exactly successful, but now I am kinda determined to come up with a better set up than stock. thanks for the insight, will share when I resolve it.

That's a shame. I just got my #20 running tonight and I'm loving it, but that switch bothers/worries me.

Good luck, I'll pass on anything I come up with as well.

Here's what I did when mine fried.

It's a work in progress. If I could machine a new firing pin that fit the stock button and a battery post/510 post it would be great.

nice. i have a friend with access to machine shop back east, i'm on the west coast, I considered asking him to machine me the parts, but seemed like overkill for this device.

if you don't mind me asking, what did you wrap the post with? silver NR wire? and what size are the screw and nut you used?

I wish I could give you more info. I wrapped the post with a piece of some wire I had left over from an electronics project, it's probably aluminum I tinned it with some silver solder after i took that picture. I just wanted to match the diameter of the post for the battery. The screw and nut were something I found after about a half hour looking in bins at Ace Hardware. They're brass and the stock spring for the button threaded onto the machine screw nicely as a retainer. It isn't perfect but it works most of the time I press the button. Just make sure if you try this that whatever you use for the button won't touch the body of the device when the button is pressed. That would short it out.

cool. thanks. and no, we don't want shorts. I may try this. for now, I managed to get the stock switch working "fairly" reliably, had to re tension the internal contact spring. I have some silver non resistant wire that would probably work quite nice for the pin diameter fix. got a buddy that machines, so I was half thinking of getting something done with him. thank you for sharing that. appreciative.
