OBSF-30-DV

1. Overview

The Sanwa Denshi OBSF-30 is the definitive 30mm snap-in arcade pushbutton, manufactured in Japan and ubiquitous in both commercial Japanese arcade cabinets and consumer fightsticks from Madcatz, Qanba, and Hori. It belongs to Sanwa's OBS (Original Button Snap-in) family and is the benchmark button against which all other arcade buttons are compared. The "-DV" suffix appended to this product ID (OBSF-30-DV) cannot be verified as a real Sanwa color code: exhaustive searches across six major authoritative arcade retailers (Arcade Renovations, Arcade Shock, Paradise Arcade Shop, Focus Attack, Arcade Express, Arcade Express EU) and a Japanese-sourced product code reference (Tops Game via mobiuslau.github.io) found no OBSF-30-DV listing anywhere. The suffix should be treated as fabricated or corrupted, analogous to the previously identified OBSF-30-SR (Product #307).

2. User Sentiment

The OBSF-30 family enjoys near-universal acclaim in the competitive arcade and fightstick community as the gold standard for main-action buttons. Users consistently praise the smooth, quiet actuation of the SW-68 non-clicking microswitch — contrasting favorably against the clickier Seimitsu PS-14-G buttons preferred by some players. At $2.85–$3.25 per button across major US retailers, the price-to-quality ratio is considered excellent. No significant complaints about the button's core design exist; the most common community discussion revolves around color preference and two-tone combinations, not performance.

3. Real-World Applications

The OBSF-30 is installed as the primary action button in the majority of Japanese arcade cabinets (JAMMA-standard layouts) and is the factory-default button in many retail fightsticks including Madcatz TE/SE series, Qanba Obsidian/Crystal, and Hori RAP series. It is widely used for main-panel button positions in custom fightstick builds, arcade cabinet restorations, and MAME cabinet projects. The 30mm diameter makes it suitable for primary action buttons (not start/select, which typically use 24mm variants).

6. Known Issues

The "-DV" suffix on product ID 314 (slug: sanwa-denshi-obsf-30-dv) is UNVERIFIED and likely fabricated — it does not match any real Sanwa OBSF-30 color code across six authoritative retailers, a Japanese product code reference, or any arcade community source. This mirrors the fabricated "-SR" suffix on Product #307. No defects or quality issues are reported for the genuine OBSF-30 family. The button body has a slight yellowing tendency over extended UV exposure (common to ABS plastic), but this is a cosmetic-only concern.

DATA QUALITY FLAG: Part number "OBSF-30-DV" is not a real Sanwa SKU. The "-DV" suffix is UNVERIFIED/FABRICATED. No retailer, no Japanese source, and no arcade community reference lists this variant. This product entry should be reconciled: either corrected to a valid OBSF-30-[suffix] or removed from the catalog. Treat as OBSF-30 generic family only.
