1. Overview

The Sanwa Denshi OBSN-24 is the screw-in version of Sanwa's 24 mm arcade pushbutton — mechanically the same as the snap-in OBSF-24 but with a threaded barrel + retaining nut instead of snap-in tabs. The "N" denotes screw-in (Japanese neji). The 24 mm size is Sanwa's standard for start/option/auxiliary buttons. It uses Sanwa's crisp built-in microswitch, in many colors. Screw-in mounting is preferred for thicker panels (wood cabinets, thick acrylic) where snap-in tabs won't grip.

2. User Sentiment

Sanwa is the benchmark for Japanese arcade buttons — the same smooth, light press as OBSF-24, with screw-in security for thick panels. Builders pick OBSN over OBSF when the panel is too thick for snap-in or they want a rattle-free mount. Standard care: confirm the panel thickness and the 24 mm cutout.

3. Real-World Applications

Start / Select / option and auxiliary (24 mm) buttons on arcade cabinets, fight sticks, and hitbox/leverless controllers — especially thick wood/acrylic panels needing the screw-in mount. Pairs with 30 mm main buttons.

5. Ordering & Compatibility

Fits standard 24 mm cutouts; the screw-in mount suits thicker panels than the snap-in OBSF-24. Same feel/microswitch as OBSF-24; pairs with 30 mm main buttons. Sold by arcade specialists (Focus Attack, Paradise Arcade, Arcade Shock, Japanese retailers). Choose OBSN (screw-in) vs OBSF (snap-in) by panel thickness; the silent equivalent is OBSFS-24 (snap-in).

6. Known Issues

No reliability concerns — Sanwa quality. Practical notes: verify the panel thickness suits screw-in, confirm the 24 mm cutout, and check the microswitch tab size matches your wiring. Beware clones for genuine Sanwa feel/durability.
