I've been trying to get the dual nub to work for some time but there always seems to be a problem. I have soldered everything correctly and is working flawlessly, the issue i am having is with the spring. I have tinned the pads on the Razor X quite a bit and well when i put it all together with the spring and the top half to the nub, it never works. Sometimes the X works, sometimes it doesnt. The triangle didn't work despite the fact that i had tested it before putting it together and it was working. Sometimes it doesn't self centre properly, it gets stuck and i have to move it to the middle myself, i'm thinking it may be that my tinning is uneven or i have tinned it too much/ too little? I'm not sure, I am getting bit frustrated as the problem is never constant on just one button, it always varies and i'm not sure why.
Thanks.
