Firing resistence

[dykealiscious]

I'd like to test the resistance of the spring in one of my switches. Obviously I'm not going to unwind it and stick it on an atty. Using a multimeter, how can I check the res of a spring or firing mechanism? Kinda an idiot with multimeters but I have one. Lol

Just set your multimeter to read ohms, and place probes on each end of the spring. It will test resistance between them

you don't have to unwind it you just need to use a multimeter and touch the probes to each end of the wire of the spring; you will basically get close to zero though; the spring would be either a steel spring or maybe a copper alloy spring; the spring might need cleaning; a soak in some liquid might clean it shiny new; vinegar should work if it's steel.

Well hell I didn't realize it'd be that simple. Thanks!

So some of my builds don't like some if my authentic mods. With spring switches. They are super sub. My understanding is if the atty resistance is lower than the spring resistance that is why I may be having some hit button issues. So I'm going to test the res and adjust the atty builds to equal or above the res of the spring and see what happens.

Any impedance will cause heat in the button. Even if it is less than the atty. what it will do is take away from the power going through your coil, and yes make for a hot button.

Only my spring loaded authentics have this issue. They are never used and spot clean. Is hopefully this will help.

Try to test the whole mod, not just the spring - but that's not exactly easy to measure - in practice what people do to make a measurement is to measure the 'voltage drop' that occurs when they fire the coil
-check battery with a meter: (i'll assume it measures 4.2 volts)
-then put battery in mod with rda on top, topcap of rda off
-put multimeter probes across the two posts
-fire the mod and chech the voltage on the multimeter.
-If the voltage reads 4.0 volts, then you have a voltage drop of 0.2 volts on that coil.

It actually does not (I mean does not help). Depends on the mod.
Most spring loaded mech do not use the spring electrically; the spring is usually on the outside performing a mechanical function, not an electrical function.
In a vamo, zmax, svd, or the typical flashlight tube, the spring at the bottom has an electrical function, and if it is corroded, power gets lost at the contact points of the spring.

The spring resistance on super to ela v2 is .4 ohms. I upped the build from .08 to .3 ish and no hot button. Now to rebuild all my pairs with a couple of other mods. Skeleton Key REALLLLY doesn't like low builds. Also a spring. El siglio also Hayes low builds but they are magnets so I can get down to about .15.

You can also hunt down different springs

All mine are rhodium over silver over copper or brass, rhodium does not tarnish and is almost. As conductive as silver
A year or so back I even had a jeweler silver plate one for me

 

[dykealiscious]

I have some 18g copper I use sometimes for springs.

If it works cool Find a good jeweler to silver plate them, they will slightly increase in conductivity and tarnish a lot slower

Berillium copper springs are the bomb if you can find them in a size you can use

I had no idea you could have that done!
