Research Notes
1. Overview
The Sanwa Denshi OBSF-24-G is the green color of Sanwa's 24 mm snap-in arcade pushbutton (Sanwa color code G = Green). The 24 mm size is Sanwa's standard for start/option/auxiliary buttons (vs. 30 mm for main action buttons). It uses Sanwa's crisp built-in microswitch (light, responsive, clicky feel) with the standard ~0.85 mm short travel. Green is purely the color option; feel and dimensions match the rest of the OBSF-24 line.
2. User Sentiment
Sanwa is the benchmark for Japanese arcade buttons — builders praise the smooth, light, responsive press and consistent quality. The OBSF-24 is the go-to for Start/Select and auxiliary buttons on custom sticks and cabinets; color choice (green here) is aesthetic. Standard cautions: match snap-in vs screw-in mounting to the panel and confirm the 24 mm cutout.
3. Real-World Applications
Start / Select / option and auxiliary buttons on arcade cabinets, fight sticks, and hitbox/leverless controllers; green suits color-coded layouts or themed builds. Pairs with 30 mm main buttons.
4. Technical Specifications
- Type: 24 mm standard snap-in arcade pushbutton (green)
- Switch: built-in Sanwa microswitch (crisp/clicky)
- Travel: ~0.85 mm (short)
- Actuation: light momentary
- Mounting: snap-in (24 mm cutout)

5. Ordering & Compatibility
Fits standard 24 mm snap-in panels; matches other OBSF-24 colors. Pairs with 30 mm buttons (OBSF-30) for main actions. Sold by arcade specialists (Focus Attack, Paradise Arcade, Arcade Shock, Japanese retailers). For a quiet build, the OBSFS-24 (silent) is the dampened equivalent.
6. Known Issues
No reliability concerns — Sanwa quality. Practical notes: confirm snap-in vs screw-in and the 24 mm cutout, verify the microswitch tab size matches your wiring, and beware clones (genuine Sanwa feel/durability differs).

Installation Quick Reference
Mounting: Snap-in buttons push into a 24mm hole from the top of the panel. Screw-in buttons thread from below and secure with a nut. Use 2-3mm acrylic, wood, or metal panel.
Wiring: Connect the microswitch terminals to your encoder or PCB. Common ground shared across all buttons. Quick-disconnect (0.110") terminals are standard on Japanese buttons.
