I have a Sanwa stick with a microswitch that seems to be acting up and not always triggering correctly – sometimes not even going off at all until I shake it up a bit.
I’m considering just buying a new PCB for it but was wondering if theres any chance of just desoldering the switch, popping it off and fixing it up a bit. Is this doable and worth attempting or should I just bite the bullet?
How is the switch acting up? not clicking? Or Clicking but no movement?
A picture of it, please. Perhaps it might show something.
The problem with an industrial grade microswitch is that the pins are not bent to the side but below it. Sure you could try to hack your way with some bits of metal to connect the regular switch to the PCB but it would not necessarily be easy to have them aligned properly like the others.
Check if the individual switch is in the sanwa catalog and if some company stocks them.
No movement upon clicking. Often I’ll have to push down farther for movement to register, someitmes significiently. Sometimes it doesn’t work at all. Always clicks though.
You’re sure its the Sanwa pcb and not the controller pcb? I’ve had something similar happen with one of my sticks and it was the controller pcb not the Sanwa.
Ive been having the same problem with my HRAP 1b.
I put a new jlf pcb in and it worked good, but then it started doing it again.
I believe it is actually the HRAP pcb so imma be putting a ps1 pcb in it some day.
I’m pretty much completely sure it’s not the PCB. if i swap some quick disconnects the controller PCB, ‘down’ will work fine and whatever I put on the ‘down’ pin will not work. Just for informations sake it’s a SF Anniversy PCB in a custom case.
I figure it either has to be the switch (probable or some messy connection between it and the pin. Out of curiousity, has anyone taken a switch off? I wanna know how I open it – or if the underside ‘open’? I figure I might as well mess with it before getting a new one. At least after getting a new one I’ll have extra switched to use as replacements too…
From what I’ve been told, this just happens to Sanwas after a while. I’m actually servicing a stick for a friend that this has happened to. He just opted the replace the whole stick.
When I was looking through the sanwa catalog that was uploaded on Akihabarashop.com I saw that the microswitches made for the JLF PCB do have a parts number, so you should be able to order them through eitehr akihabara shop or if not, lizard lick might be able to get them for you as well.
Hm, maybe I’ll consider that. They look relatively easy to swap out.
