Magnetic upgrade???

[Richstag]

Hello,

Here is a quick one. Hope this is the right spot to start the discussion.

This is in no way all inclusive to my particular mech, nor do I want the discussion to be, but I am using a Surefire knurled satin king mod. Just in case this does matter for this comparison.

So I bought a magnet "upgrade" with two magnets for my king. I feel like it is now less repeatable performance. With the spring it fires exactly the same every single time. Not only that, but it feels stronger with the spring.

My question is, is a magnetic upgrade always an upgrade? If so, what is going on here???

Thanks,

With my fake Nemesis, the magnets I got from SlowTech fit a bit too tight and made it function worse than with the spring. Only after I increased the inside diameter of the magnets {with a dremel/sanding drum} did it work the way I feel it should.

Hope this helps!

It fits perfectly diameter wise. Seems to allow the same amount of travel too. I can't figure it out.

It's an upgrade when it works the same performance wise, yet eliminates the mechanical scrunching of a spring, both by feel and by sound. You said the travel is the same, but is the tension of the throw the same too? Is there some way to adjust the distance between the magnets?

It could be the spring was helping to complete the circuit by providing an extra piece of contacting metal in addition to the copper contacts. The magnets shouldn't actually touch when fired, so it is up to just the contacts.

Also, a spring has some bias to it, that when depressed the switch post is not absolutely level and hits the the switch tube a certain way relative to the spring. With magnets, the post is floating and performance is more dependent on the tolerances of the switch parts.

Lastly, are all the copper contacts clean? If it is hitting inconsistently, that means the connections aren't making that great of a contact which leads to more arcing which just makes them dirtier.

It is not a lost cause, but it sounds like it needs some tweaking.

Yeah man, I keep this thing spotless. I put the magnets in during my weekly breakdown and clean. I mean better than new spotless too. No it doesn't have the same tension. It's easier to push but I feel to make the same contact I have to press it harder towards the end.

Sounds like you need to get stronger magnets for it, that will increase the stiffness of it.

I have heard of people using 3 or 4 magnets in their mod switches, but obviously space is sometimes the limiting factor.

 

[Richstag]

Yeah, I got these from fatdaddyvapes and it will only fit two. Maybe its just good enough with the spring. Honestly I had zero complaints, I just wanted a spare. Can't get a hold of surefire to save my life.

Someone say something about magnets??

Have you seen the magnets that stick to concrete???

So tell me something about magnets...

IMO, this is the answer ^^^. I had the same experience with my Nemesis. Put magnets in and it didn't take long and I was getting poor performance and miss-fires. Cleaned the switch parts and all was well for a few weeks and the same thing happened again. Previous to putting the magnets in I had been using it for a couple of months with no issues.

Looking at the switch design it became obvious to me the spring was part of the switch circuit. Without it there all you have is the outside diameter of the switch plunger making contact with the inside diameter of the surface it's sliding in.

I kept the magnets because I like the way they feel in the switch, but I accept that I need to clean more often because of them.

Thats good info and makes sense on the design. Thank you. I am testing it with the threads and all contacts clean as can be though. Its probably just not as good of a system for this mech, unfortunately.

I had a somewhat similar situation with a mech before. Another possible solution I found was, if you have room in your mech, put a pair of the magnets in and also run the spring with them too. It solved all issues. Had the firmness of the spring and smoothness of the magnets. Best of both worlds.

 

[Richstag]

Hmm, I think this would be a challenge but maybe a completely different spring. Smoothness is the same for spring or magnet on this setup. I was expecting to put the magnets in and have a huge upgrade.
