The switch looks kind of simple, doesn't it?
But in reality, it's amazingly complex!
One thing that most people don't think about is that most switches have springs in them, and that spring carries the current from the switch contact to the body of the PV.
Well, those springs really sink a lot of current and rob the PV of power!
With the magnetic switch, there's no spring, so has anybody wondered how the current conducts to ground?
The Switch button has a slight amount of "play" in it... so when you push the button it tips a little to the side, and when the side of the button scrapes along the side of the switch housing/battery cover... it makes electrical contact across a pretty wide area conducting WAY more current than a spring ever could.
So long story short, the scraping is normal and entirely necessary!
People have asked why I don't use a flat top screw on the switch... and the reason is that a flat top can prevent the switch button from rocking to the side, and prevents it from firing.
A lot of thought went into something that looks really simple.
And some do make a little more noise than others... perfectly normal
Hi Zen,
I've been having some misfiring issues in my mini (and flooding also, but I learned and read that I should not left my Mini lying down if it has liquid in the tank), I indeed wondered about how the button closes the circuit when is pressed

(I posted on the Zenation-Home of the Zenfidels Group -> Issues for the early adopters)
This is my first mod that uses magnets instead a spring in the button, so I thought it worked on a different way (my personal conclusions), I saw that I'm wrong, however due the missfiring problems I used an ugly solution

(everything inside the button is clean, the battery poles are clean, the button on my mini came with 2 magnes inside)
I wondered, because the way that the button acts to close the circuit, if it could be possible that maybe the button is working at an angle position, that could cause the screw head loses contact (due there are not many contact points to the negative pole of the battery when the buton is pressed (posted some pictures on the group)?
