I do not know if that is the correct term, but the rubber membrane in a controller that sits between the dpab and the contacts on the PCB is what i am after. The hori commander pro 3 for PS3 has been discontinued and cost around £50 not including shipping after doing a quick google.
The problem i have discovered with this pad (my 2nd one) is that the dpad rubber membrane contacts will breaks off after heavy use and will no longer register your inputs as a result.

The dpad membrane in this pad is circular and the individual contact points are elevated in the rubber and form a ‘hump’. when you push the dpad the hump is pressed in making a contact with the pcb and the signal is made. It’s this part that breaks and it separates as a perfect circle as if it was from a cutout where there were perforated edges.
I have glued it back in place but that has made that contact point slightly stiffer on inputs/press down and I suspect it will likely happen with the outer 3 contact points overtime .
I need help finding a suitable replacement membrane or if someone has ‘leftovers’ from padhacking this pad to an arcade stick etc.
I think nintendo ds/3ds conductive pad might be a suitable replacement but none seem to be the right shapes as i’ve been browsing ebay for sellers that sell ds,360 pad replacement parts.
I already asked hori support, stated they don’t sell the parts etc.
EDIT:
I think all the suggestions of possible repair are all acceptable
- replace original membrane with a dpad membrane from a 360 pad as the contacts in other dpads failed to register press inputs
- replace with tact switches (unsure on the correct tact switch sizing atm)
EDIT 2: Solutions with pictures.
replacing the og membrane with dpads from other controllers. first things first, you can probably reuse your existing dpad membrane. It the dome has been broken cleanly like the picture above using crazy glue you can simply reglue the dome in place. To do this i suggest using thin tweezers and very little super/crazy glue, if you use too much the rubber will harden lessening the give when pressed. The contact sits on a thinner rubber mound, you only want the glue to sit on the lip of this mound to reform the seal.

If only one of you contacts are broken at this point you may want to simply dap small amount of glue at cardinal points around the other contacts. This is optional however and you may not need to do this however on my dpad two other contacts were beginning to break so i opted to dap the glue where there were visible breaks.
This is what made me one to examine other options, an absolute resolution.
for other membranes i tried a 360 pad as suggested by @Tarek but i didn’t like this at all. as i mainly play tekken, doing clutch DF for iws stuff was a chore, inconsistent and pure headache.
here is what the 360 dpad mod attempt looked like. (Tarek might say this was not how he did his)

so i tried a ps3 dpad, both these dpads came from ebay as replacement parts. I messed up a bit on this on P1 fwd contact point, removing after the glue has set seems to be a write off on these dpads. so check thrice before setting.

I will add the tact switch stuff later…
