OBSF-24-B

1. Overview

The Sanwa Denshi OBSF-24-B is the blue color of Sanwa's 24 mm snap-in arcade pushbutton (Sanwa color code B = Blue; K = Black). 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. Blue 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 (blue 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; blue suits color-coded layouts or themed builds. Pairs with 30 mm main buttons.
