Sanwa Denshi [24mm] SOLID COLOR Pushbutton [ OBSF24 - XX ]
New (old stock) color variant: Dark Hai (all grey) - These were made specifically for Hori many years ago for their arcade sticks when they used Sanwa Denshi parts in their SA line. Not a big deal as it's a new color, but pretty neat that these are around and whatever is left, is left. No more will be made.
Sanwa Pushbuttons (24mm Size) NORMALLY used for the START/SELECT on the Hori Sticks. If you want the PLAY buttons get the larger 30mm size.
