For some reason I read that you were knew to orion. Ok, so the switches are burning up without you even pushing the button, Am I correct? and when you read the voltage it's reading at 2.1volts? Did you buy the switches directly from vaporwall brand new. It could be an error in the way Palilop (sorry for the misspelling) is making the switches. I've only had my orion a few months and I bought 3 switches from him so far just to stock pile and they all worked fine but this was months ago. You need someone with some real expserience to help you. While were at this, do you think you could read my post above and give me any pointers?
First, from everything ive ever read all switches ultimately come from him, only one that makes them, i do know that both of these switches are brand new, but yes older, as I'd imagine all are though. It is possible that since i got them both from the same buddy they were from the same bad batch if thats possible. Im not a member of the site you referenced but i think they hand pick people, so i imagine i will be on some never ending waiting list to get in (only come to this conclusion based on others experience)
Next advice for you, i took out my stupid spring and washers, i use the same nuts as your top nut on your post, only 2 of them and put wire in between the 2. So yes you wil have 3 total one at bottom and two at top . Next, i dont use mesh any more I use a steel cable (bicycle brake cable) which is down in the tank obviously not touching the bottom, i put hollow ekowool on top of the cable where i wrap the wire around, no hot spots unless its just the wire not spaced apart . If youre not gonna make the conversion my advice is oxidize the crap out of your mesh and / or lean the wick towards the post, also one tip is to make sure you go on the inside of the last wire wrap and then around the post, not where the wire comes off the top leg from the wick and the around the outside of the post, go inside then around. As far the extra metal thingy i havent a clue without pics ... cheers!
