PS2 repair joystick non original ps2

[cloudff7]

Is it possible to repair a (non-original) PS2 joystick where the buttons sometimes fail or require forceful pressing to function?
I have several here, or will they just end up in the trash?

If they need a lot of pressure to work, I'd say they're most likely dirty over the carbon pads. I don't quite remember if the PS2 uses rubber domes with a contact underneath or if it uses a two layer flex circuit, but either way both can be cleaned. You could disassemble them and clean the carbon pads and under the rubber domes with some isopropyl alcohol and a cotton swab. At least that's what I do.

That should work fine too
