SDB-202A-24

1. Overview

The Crown/Samducksa SDB-202A-24 is a 24 mm translucent (clear) arcade pushbutton from Crown/Samducksa (Korean arcade-parts maker, a competitor to Sanwa and Seimitsu). A defining trait of the SDB-202 line is that it uses a Cherry MX-style keyboard switch inside (rather than a leaf/microswitch like Sanwa) — giving a shorter travel, more tactile/keyboard-like feel, and a swappable switch for tuning the feel/force. The clear/translucent body is made for LED backlighting. This is a 24 mm (start/aux size) button; the same design also comes in 30 mm.

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 — the Cherry MX switch means faster actuation and the ability to swap the switch (e.g. to a lighter/heavier or silent MX) to taste. The translucent bodies look great with LEDs. Considerations: the feel is noticeably different from Sanwa/Seimitsu (love-it-or-not), and you confirm mounting style (screw-in) and the 24 mm cutout.

3. Real-World Applications

Start/select/auxiliary (24 mm) buttons on arcade cabinets, fight sticks, and hitbox/leverless controllers — especially LED-lit builds and setups wanting a keyboard-switch feel and swappable actuation.

5. Ordering & Compatibility

Fits 24 mm panel cutouts; pairs with 30 mm main buttons for a full layout. Sold by arcade specialists (Arcade Renovations, Focus Attack, Paradise Arcade, Korean retailers). The swappable Cherry MX switch lets you change feel/force. Confirm screw-in vs snap-in and the 24 mm cutout; translucent body suits LEDs.

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 and switch/force when ordering.
