PLASTIC springs...better?

I was reading another thread on the forum from someone who was having trouble with his ecig misfiring in his pocket and he believed it was caused by the metal spring touching the inside metal wall of his ecig, or maybe even touching the button on the battery.

I was thinking, is this why David puts that rubber or delrin-like cap on the top of the spring, so the spring cannot come into contact with other metal parts of the ecig?

Well, tell me if this one fellow's solution to the whole problem is a solution...or not, which can be found here:

Funny that I should come here to post my review of the P16 that I got today and find a post talking about the springs I was talking about on the PS forum last night.

I really don't think that is going to be an issue with my P16 because I don't think the spring actually touches the battery's end. Correct me if I am wrong but isn't the spring held in place by a step machined into the inside wall of the tube? In the Prodigy switch mechanism the spring actually holds the battery as well as pushing the button outwards.

This is my first STM device so I am not sure which device in particular you are talking about.

vapn, you the man! Now, it is my conclusion that it doesn't matter that I've never had a misfire caused by the spring in any of my 4 super-duper 6V vaping devices. What does matter is the possibility that it 'could' happen, hence the reason for David's construction of that little rubber cap?

So although I believe a metal spring can behave itself and never touch anything that would cause a misfiring, couldn't this potential problem just be solved by using a good plastic spring?

P.S. What's an STM device?

In theory yes.

STM= Super-T Manufacturing

The Old S6 switch design was different, it had a plastic insulator to seperate the spring from touching the battery.

The new Precise design is completely different (as vapn mentioned), there is no plastic insulator and you want the spring to touch the body, as with the new design, it has double contact areas to make the ground, both via the button via friction and through the spring touching the body and switch sumulaneously.

Hope that helps

AAA Yes I see now. So you have designed in a redundant path for the current to flow. I know I have had issues with mechanical switches. If the button is perfectly centered in the assembly it isn't making proper contact and allowing the current to pass to the body. Very cool and probably why I am seeing more performance.

As I understand it, it was the metal spring touching the inside walls of the ecig that was the problem, not so much the spring touching the battery. The batteries on my Icon have insulation around the rim of their bottom end, protecting them somewhat from the spring. As far as I know, that's pretty standard on batteries.

The spring on either the s6 or the Precise can touch the wall, no problem. What they can't touch, however, is the bottom of the battery. That is why the Precise utilizes a machined in ledge to prevent this, and the S6 utilized a plastic insultor.

Those fixes make sense. Would a good plastic spring also be a solution?

On the S6 one could theoretically use a plastic spring, not on the Precise though as electricity flows through the spring.

That's good to know. And I don't really need a plastic spring on my Six because the metal one has never posed a problem.
