The Sanwa SW-68 microswitch is used in the OBSF-30, OBSF-24 & OBSN arcade buttons. This little microswitch is what gives Sanwa's arcade buttons the rapid yet smooth response we all know and love. The SW-68 is the ideal replacement for an old, worn out button that has seen better days.
Well I got them just in case one broke. That hasn't happened yet

I swapped these switches into my Qanba Q2 Glow LED buttons after one of the stock switches somehow fell to pieces. They fit straight into the LED buttons without any modification, even the buttons that were previously working are 100x better now that they have that Sanwa feel.
