tube mod switches.

[Lance_Wallen]

Lookin for osme ideas for tube mod switches, appropriate amperage, etc. Need something low profile that'll fit in a 1/2 inch tube (14500 tube mod). Been digging through multiple sites, just figured I'd ask and see what other people are using or if any of the more experienced modders have a 'fav' out there.

For 1/2" tube its a pretty limited selection if mounting the switch inside the tube . Most of the time you will have to go with a touch switch , tact switch with mosfet or mechanical . Their are no 3a+ switches that are really small .Smallest in depth will enough amp rating will probably be the horn switch madvapes sells or radioshack switch . You can gain a little more space by bending the pins outward

RS sell a few types of tactile switches that are small enough that you could mount a mosfet on the back of it and it would fit in a 1/2" tube

 

[Lance_Wallen]

hrm, rather not use a mosfet if I can avoid it. the less complicated it is the better. maybe I can rig something mechanical

 

[Rocketman]

You could probably scramble wire a mosfet and a resistor right on the back of a tact switch.

Wouldn't something like this work?

That's a good idea cassie. Shame, but I haven't seem the Riva boards on sale. No PWM, right?

A lot easier to do that this (3/4 inch tube for an 18650)

What is the mosfet (chip) and the switch in the (3/4 inch tuve for an 18650). It looks really simple, plus I noticed it is rated at 5 amps.

 

[Rocketman]

Not a mosfet. Just a microswitch "adjusted" to fit in the tube and a button fashioned out of the head of a nail.
Rounded off on the outside.

The switch is in the center tube and a matching hole is made in the endcap.

When done it looks like this:

 

[Lance_Wallen]

yeah, seem to be a number of decent options for the 3/4 inch tubes, 1/2 is proving to be more complicated.. I gotta find a suitable switch though, i'd really rather not use a riva/ego board. I hear a lot about rivas/ego boards burning up and I don't want all those other 'features' like draw duration, etc. Thanks for the suggestions so far guys, if I find osmething good I'll post it.

 

[northhar]

Okay I see now that it is explained. It is very neat, I think I'll try that.

Thanks

Niiiiiiice.....and will last freakin' forever

 

[Lance_Wallen]

I like what rocket posted, just wish I could fit it in a 1/2inch tube lots of options for my 18650 mod not a lot of switch options for my 14500 mod.

 

[Lance_Wallen]

wonder how hard it'd be to make my own mechanical switch and keep it isolated from the mod body . been searching for three days now and can't find a suitable switch

This 3 amp C&K will fit (8552MZQE2)
Just tried it in a 1/2" copper tube. You will have to bend back the solder tabs and the threaded bushing must completely stick out of the tube.
Digi-Key - CKN10193-ND (Manufacturer - 8552MZQE2)

The thread length is 6.35mm and a little more than half will protrude due the the inside curve of the tube. Approximately 3.5mm will protrude of the threaded bushing. The nut will cover a couple of threads. This is without the plunger length. The plunger is 3.81mm.
