The Sanwa OBSF-30 is a 30mm snap-in style arcade button and features a built in microswitch with 2.8mm terminals. These are the buttons of choice for fighting game enthusiasts and are the same buttons that are used in QanBa and Madcatz fight sticks. These high quality arcade buttons are imported direct from Sanwa Denshi Co in Japan. This button is ideally suited for mounting in metal control panels, with a thickness of approx. 2 - 4mm. Each button has a plastic clipper on either side that locks into place when mounted on a control panel or fight stick.

    Clearly genuine products with manufacturers branding and quality build with easy installation and good performance on my Neo Geo Arcade Stick Pro. Highly recommended.

    I was a bit disappointed when I first saw these buttons as they looked kinda cheap and toyish, although I'll say that they looked super cute in their little single plastic bags. Once I replaced the old busted buttons on my old MVS though, they convinced me right there and then. They look amazing, they feel great to push and they are SUPER sensible, feels like you could press them by sneezing in the next room sometimes. Great buttons for a great price!

    Used these to replace the stock buttons in my PS4 Venom Fight Stick. Good upgrade, well worth the time and cost. Much snappier.

    A doddle to swap out, literally, unclip the old ones and snap in the new ones. Couldnt be easier.

    Sanwa OBSF-30

    These buttons are sublime, they are so responsive, I reckon blowing in them might even make them register!! They offer fantastic value for money and are premium quality. And, the fact you can swap and change them not only so simply but, you can have a different coloured plunger to that of the base is EPIC!!! I actually prefer the loud version too after seeing a review of the silent equivalent!! Excellent all round!!! 5 stars!!!

    These buttons can take a beating and a half

    It seems like these buttons have figured out the secret to eternal youth because they certainly seem like they don't lose their day one condition and feeling no matter what you throw at them.
