Sanwa OBSF-24 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-24 is the 24 mm sibling of the flagship OBSF-30 — Sanwa's standard snap-in button for Start / Select / option / auxiliary positions. Same built-in Sanwa microswitch and light crisp feel as the 30 mm, in the smaller 24 mm size that pairs with 30 mm mains. Snap-in mount, convex plunger, many colors.
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.
