that should works
unless they were dicks and somehow the circuit depends on the specific resistance of the tooled pads
seems like effort for no gain

it has carbon in it
its not a very good conductor, but it works for this
if they dont get dirty, theyre very reliable, very low cost
the rubber pad is likely a complicated set of tools to manufacture, im guessing towards $100K, so you dont see it much except on things that are made in very large volumes
also all the surrounding mechanicals need to be of moderately tight tolerances, or shit like that doesnt feel right, button wont always work

kinda
but yes you wear away the PCB
the carbon rubber pads are very cheap if you are making tens of thousands of devices
and they wont wear the PCB usually
sometimes, but its probably just a cheap PCB

pure alcohol, if you have it
put it on a little piece of cloth or paper towell and just wipe all the pad traces on the PCB until they look clean
like first aid kit stuff
ha, no im broke
beer is cool
just try doing the rubber first tho
then try shorting out the finger traces on the PCB with metal keys or coins
that short work but it wont last forever, eventually you wear away or break the traces
*that should work
like instead of pressing the button
just hit it with a coin
electronically, its the same thing
or close enough

cleaning it will prob fix it
see how the button have metal traces like interlocking fingers?
just short those fingers out to press buttons
right
connect them with something metal
complete the circuit
nothing
the fingers arent connected, the pads under the buttons connect them
thats why they dont work when theyre dirty
yeah, but youre not an asshole so youre a lot easier to deal with than people who just know a little bit of electronics
yeah because rubbery
this problem goes back to the 80s at least haha
so:
1) clean the rubber pads under the button
if that does not work, 2) carefully clean the pads on the PCB
use a damp cloth, try not to get it on other parts of the device
clean water is pretty harmful, but dirty water can be conductive, mess with electronics, and your thing is filled with dust most likely

well yeah theyre dirty, most likely
if the carbon pads are covered in dust, they might be too resistive to short the traces proper
theyre not very conductive to begin with
thats prob enough
yup
avoid water
itll mix with the dirt and if it gets on the electronics itll fuck all sorts of shit up
if you have to tho just make sure its completely dry before reassembling and keep the wayer of the main PCB with the digital chips and stuff
worst case tho, just rip the button off or use it as bare PCB, in a plastic ziplock bag, and shirt the button traces with a coil or something
keys, whatever
and plan on buying something new real quick
*short the button traces with a coin or something
but first just do what timecop said, find the rubber thing under the bottons and clean it

also, if you need it and cleaning doesnt help, consider using it in a ziplock bag, with the button pads pulled off, either using the existing tactiles or replacing with *anything* that switches
you can use a wire jumper and short across the pins if the tactiles themselves are fucked
im not familiar with the device so i dont know how practical what im suggesting will be
timecop: no little click buttons
little metal squares with a circle button that pushes in less than a mm
that either have a click feel or you can sometimes hear it
oh fucked up
thats not tactile switches that carbon pad switches
just short out those pads with anything
if you can find 90% or 100% isopropynol (first aid rubbing alcohol), clean them with that
youve never fixed an NES controller?

arooni-mo: disassemble, remove PCBA, replaces tactile switches with dimensionally identical parts, reassemble, done
alternatively, you get a replacement PCBA, and just swap it out, thats the service tech solution
you would have to somehow social hack it from the company, maybe ebay, or buy a broken one for parts
if you absolutely need functionality, you can removed the external button pads, so the tactile buttons are exposed
really, try cleaning under the pads and look for debris before anything else
right
there could be a mechanical interference problem
right and see if there is crud
or if you can see inside the seams from the outside, maybe run a needle through them, see if anything comes out
oh
yeah dude clean it, tactile buttons are very short throw, so very sensitive too all sorts of mechanical issues
