Description - Sanwa OBSF-30 Japanese Arcade Button

These are the most used push buttons in Japanese arcades, the Sanwa OBSF-30 push buttons. These push buttons are perfect for arcade fighting games such as Mortal Kombat, Street Fighter II, etc, due to its fast action springs.

The Sanwa OBSF-30 are the standard push buttons used in Arcade Fight Sticks by brands such as Madcatz, Qanba and Hori amongst others. They are also perfect for making modifications to Mayflash control panels and for installing in metal control panels or Controls Panels that do not have much space under the base.

With a diameter of 30mm the Sanwa OBSF-30 is soft to the touch and a very silent button. This is a very fast action button as the springs inside it are super short and sensitive. Just a little pressure is needed to activate them. Top of the line, the OSBF-30 is a button that will last you a lifetime.

This push button is ideal for mounting on metal or thin wooden control panels. The panel needs to be up to 3.7 mm of thickness and with a 30 mm mounting hole. The Sanwa OBSF-30 is super easy to install as it has a a plastic clip on each side that locks the button when mounted in the control panel. We also sell the version of the OBSF button with a 24 mm diameter. The OBSF-24 is normally used as a start, select, credit or special function button.

If you want to install Sanwa buttons on thicker panels, we recommend using the OBSN-30 variant with screw. Besides having a screw that makes its installation easier in wooden panels, it's got a longer length.

Mounting Information

To install the Sanwa OBSF-30 push Button, you'll need 2.8mm wiring as that is the width of the button terminals. If you purchase one of the encoders we sell at Arcade Express, be sure to select the option with 2.8mm wide terminals. You can also purchase extra 2.8mm wiring for the Zero Delay or the Xin Mo from the links below: Zero Delay / Xin Mo.
