Sanwa Denshi OBSF-30 — OBSF-30 Snap-in Arcade Button (30mm)

主な用途

The OBSF-30 is the default button in Vewlix and Blast City cabinets, Qanba and Hori fightsticks, and most custom arcade builds. Available in a wide range of colors. Snaps into a 30mm panel hole with no tools required.

模倣品に関する注意 Medium リスク

Fake Sanwa buttons exist on AliExpress and Amazon marketplace sellers. Genuine Sanwa has SANWA logo clearly molded inside the button rim, consistent spring feel, and smooth microswitch action. Fakes often have scratchy feel, inconsistent actuation, and blurry or missing logos. Buy from Focus Attack, Arcade Shock, or authorized dealers.

“Sanwa OBSF-30 for speed and sensitivity. The 0.85mm travel is insane — you barely touch them and they activate. Seimitsu if you want a bit more resistance so you dont accidentally press during neutral.”
