Korean Samducksa Arcade push button model SDB-202M of 30mm with Cherry MX Speed Silver microswitch and metallic color.
Research Notes
1. Overview
The Crown/Samducksa SDB-202M is a 30 mm metallic-finish screw-in arcade pushbutton (Korean-made by Crown/Samducksa, a competitor to Sanwa and Seimitsu) — the main-action-button size. Its defining feature is a Cherry MX-style keyboard switch inside (the SDB-202 line is "Cherry series"), giving a shorter-travel, more tactile/keyboard-like feel and a swappable switch (e.g. Cherry MX Speed). The metallic (M) version has a metal-look plunger (finishes like Gun Metal), and it's screw-in for secure mounting on thicker panels.
2. User Sentiment
Samducksa/Crown buttons have a devoted following among fight-stick and hitbox builders who want a snappier, shorter-travel press than Sanwa, plus the ability to swap the Cherry MX switch to tune feel/force. The metallic finishes are prized aesthetically. Considerations: the feel is noticeably different from Sanwa/Seimitsu (love-it-or-not), screw-in mounting needs the right panel prep, and Cherry-switch swapping is a plus for customization.
3. Real-World Applications
Main action buttons (30 mm) on arcade cabinets, fight sticks, and hitbox/leverless controllers — especially premium/metallic-look builds and setups wanting a keyboard-switch feel and swappable actuation.
4. Technical Specifications
- Type: 30 mm metallic screw-in arcade pushbutton (Crown/Samducksa SDB-202M)
- Switch: Cherry MX-style keyboard switch (swappable; e.g. MX Speed) — shorter travel, tactile/keyboard feel
- Finish: metallic (e.g. Gun Metal) plunger
- Mounting: screw-in (30 mm cutout)
- Sizes: 30 mm (this) and 24 mm variants (cf SDB-202A-24 #496)
5. Ordering & Compatibility
Fits 30 mm panel cutouts (screw-in). Pairs with 24 mm Samducksa/other start-aux buttons. The swappable Cherry MX switch lets you change feel/force. Sold by arcade specialists (Paradise Arcade, Focus Attack, Arcade Renovations, Korean retailers). Confirm screw-in vs snap-in, the 30 mm cutout, and the desired metallic finish/switch.
6. Known Issues
No notable reliability issues — the Cherry MX switch is durable and swappable. The main consideration is that the feel differs from Sanwa/Seimitsu (shorter, more tactile), so it's a preference choice; confirm mounting style, cutout, and switch/finish when ordering.
