1. Overview

The Crown/Samducksa SDB-202-C is a 30 mm clear/translucent screw-in arcade pushbutton (Korean-made by Crown/Samducksa) with a transparent (convex) coloured plunger designed for LED backlighting. Like the rest of the SDB-202 "Cherry series," it uses a Cherry MX-style keyboard switch inside — giving a shorter-travel, tactile/keyboard-like feel and a swappable switch. The "C" (Clear) version diffuses an LED behind the button; it's screw-in for secure mounting and comes in translucent colors (e.g. Clear Blue). It's the clear counterpart to the metallic SDB-202M (#536).

2. User Sentiment

Popular with fight-stick/hitbox builders who want a snappier, shorter-travel Cherry-switch feel plus RGB/LED shine-through from the clear plunger, and the ability to swap the Cherry MX switch to tune feel/force. The feel is noticeably different from Sanwa/Seimitsu (preference-dependent). Great for LED-lit custom panels.

3. Real-World Applications

Main action buttons (30 mm) on LED-lit arcade cabinets, fight sticks, and hitbox/leverless controllers — the clear/convex plunger shows an LED behind it, with a keyboard-switch feel and swappable actuation.

4. Technical Specifications

• Type: 30 mm clear/translucent screw-in arcade pushbutton (Crown/Samducksa SDB-202-C), convex plunger
• Switch: Cherry MX-style keyboard switch (swappable) — shorter travel, tactile/keyboard feel
• Lighting: clear/translucent body for LED backlighting
• Mounting: screw-in (30 mm cutout)
• Colors: translucent options (e.g. Clear Blue)

5. Ordering & Compatibility

Fits 30 mm panel cutouts (screw-in). Clear body accepts an LED behind the button. The swappable Cherry MX switch lets you change feel/force. Sold by arcade specialists (Paradise Arcade, Focus Attack, etc.). Confirm screw-in vs snap-in, the 30 mm cutout, and the translucent color/switch. Sizes: 30 mm (this) and 24 mm.

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); confirm mounting, cutout, LED fit, and switch when ordering.
