My original Pac-man controller doesn't want to go right anymore, the leaf switch isn't making enough contact. (Also one of the leaf-switch buttons is acting flaky.) I tried bending the right leaf switch a bit without disassembling, but it doesn't help. I wondered if there was a way I could fix existing leaf switches through bending / cleaning? If not, would it be better for me to try to replace leaf switches, or just get a whole new controller? I tried to find an original Pac-man controller for sale but didn't have any luck so far.
