Thanks for the tip definitely a lot easier on the hands

My maraxus has been sitting collecting dust since I got it.
The button would get so hot so fast it was impossible to move my finger without getting burnt.
I read this thread and decided it was worth one more try to make it work.
And it worked beautifully!
No more sparks, no more hot button, no more problems at all!
AMDTrucking, I owe you a beer sir!
If you ever get around the Knoxville, TN area you let me know, lunch and drinks will be on me!

I'm always glad to be of help.

And thank you for your kind words.

Be safe.

A mate gave me his Maraxus to have a look at because he'd been getting constant misfires with it.
I pulled it apart and gave it a good clean up, then made a small brass washer to fit into the delrin cap as was shown here.
It still misfired. I then swapped out the spring from my Sentinel M16, which is a bit thicker and stronger... more misfires.

I've pulled it apart again and again and had a really good look at it.
It seems like the problem is more of a design flaw with the switch, rather than a "missing part" or weak spring.
I'm no designer, engineer or electrician, but this thing has no contact shoulder for the gold coloured brass button to make contact with.
So, when you press the button, the other end of the button makes contact with the negative terminal of the battery. The battery tube and button housing form part of the negative "circuit"(?), the only contact that I can see the button making with the button housing is where the lower section of the button touches the sides of the housing. In the case of my mates unit, the button is a loose fit inside the housing and I believe this is causing the misfires.
If their was a conductive screw in shoulder that sat above the lower section of the button for it to make contact with, I think it would solve the problem altogether.

You missed the whole point of my post.
1. The brass washer is sitting very snug inside the switch making constant electrical contact with it.
2. High conductive Silver Coated Beryllium/Copper Spring is making a perfect (permanent) connection between the switch button and that brass washer.
In this situation there is absolutely no possibility left for misfires due to a faulty switch.
