Seimitsu PS-14-GN Solid Color Pushbutton (30mm - Screw On)
Solid color screw on pushbutton 30mm in size. These are great to be used for custom modded sticks that are various depths on the control panel. While Sanwa Denshi has the majority of it's users for the snap in solid pushbuttons, Seimitsu pretty much dominates this sector as they offer a larger range of color choices.
This is the main play pushbutton size found in QanBa, Hori and Mad Catz fight sticks.
