Computer case part DimasTech PD024 silver — chassis accessory, single unit

DimasTech PD024 silver is a computer case part supplied as a single unit and finished in silver. Designed as a chassis accessory for PC enclosures, this component functions as a push-button with integrated LED ring illumination. The button offers momentary action and is intended as a replacement or upgrade part for compatible computer cases where a silver-coloured control element with yellow illumination is required.

Advantages

The push-button features a 19 mm cutout diameter and an illuminated yellow LED ring powered at 12 V, providing visible status indication. It includes separate contacts for normally open (NO) and normally closed (NC) circuits plus a dedicated contact for the power LED, enabling flexible wiring options. Rated for an estimated lifetime of 40,000 hours, the component is suitable for repeated momentary use and straightforward to install in compatible chassis openings.

Suitable for

• Replacement of a damaged or worn push-button in a compatible PC chassis
• Adding an illuminated control button to a custom-built desktop computer
• Upgrading case front-panel controls to a silver-finish accessory
• Integrating a momentary switch with separate NO/NC circuits in DIY projects
