Sanwa OBSF-30 convex style buttons. Ideal for playing fighting games, installing in candy arcade cabinets and for modifying Arcade Fight Sticks.
Research Notes
1. Overview
The OBSF-30 is Sanwa Denshi's flagship 30 mm snap-in arcade pushbutton — the de-facto standard main-action button in Japanese-style arcade cabinets, fight sticks, and leverless/hitbox controllers. It has a light, crisp, short-travel actuation via a built-in Sanwa microswitch, a convex plunger, and snap-in tabs for panels up to ~5 mm. Sold in a huge color range. This is the reference button the OBSN (screw-in), OBSC (clear), OBSJ (metallic), and OBSFS (silent) variants are all derived from.
2. Technical Specifications & Compatibility
See the structured specs on this page (diameter, mounting, plunger/finish, microswitch). These are standard arcade-button form factors — confirm the panel cutout (30 mm / 24 mm / 18 mm as applicable) and the snap-in vs screw-in mount for your panel thickness before ordering.
