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.

    Homemade controller

    Best buttons I’ve tried. I’ve tried a lot too.
    Super sensitive and reliable. They take a hammering and have not failed me at all.
    Arcade world is the best in the uk. Helpful, honest, well packaged and with great customer service and fast too. 10/10 on all counts. Buy with total confidence.
    I’ve ordered direct from Japan before and arcade world is leagues ahead. Thank you.

    Button feel is excellent and the value is really good. Don't buy chinese cheap buttons like I did they are horrible.

    Feel just right - perfect

    Posted by Kalwant on 22nd Feb 2019

    I bought a Hori RAP4 Kai and felt the Hori buttons were a bit mushy. I swapped them for these and they feel just right. They've got more shape and form to the way the button depresses and springs back. I tested them by leaving some Hori buttons in and comparing them. The Hori buttons aren't bad but these are superior. The quality feels that bit better. I tested them by playing some games on MAME like R-Type, Truxton and I can fire faster with the same effort. I'm a light button presser, so when firing fast, I tend to have the button constantly depressed, allowing it to raise just enough to disengage the microswitch before pressing it again. A very high quality product.

    The Real Deal!

    Posted by Adrian Błaszczyk on 26th Jun 2018

    The buttons came quickly despite it being an international parcel. They are genuine, as compared with my Mad Catz Soul Calibur Fightstick. The Royal Blue is an exceptionally great shade! The Pink one is also very pleasant to look at.

    Great replacement for Madcatz TE buttons

    Posted by Uncle D on 10th Apr 2018

    Nothing to say but it's what you would expect. A bit tight, but once in, works great.

    Replacement for Venom PS3/PS4 stick

    Posted by Stormy on 12th Mar 2018

    I replaced the stock buttons on my Venom PS3/PS4 FIghtstick with Sanwa buttons and while it wasn't a massive difference, it was still noticeable, because the Sanwa's aren't as squishy as the stock ones. And you can choose from a massive variety of color combinations, which is cool.
