I have a hori rap3 stick with sanwa parts , kind of used up, things still work. im just curious to how long do sanwa buttons last or hardware or should i look to swap out parts every so often?
The button switches are good for about a million presses or so. The switches in the stick are good for about ten million presses, give or take. What all is failing? How does the spring feel? Maybe a new tube of molykote is in order.
When they do wear out, you can replace the microswitches rather than buy all new buttons.
