The **YB215CWCPG01-5F-JS** is a high-quality, panel-mounted push-button switch manufactured by **NKK Switches**. It belongs to the YB2 series, specifically designed as a tamper-resistant, splash-proof, and illuminated control component. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 3A @ 125V AC / 3A @ 250V AC | | **Voltage Rating** | 30V DC | | **Illumination** | Green LED (5F) | | **Cap Color/Material** | Clear Lens with White Filter / Polycarbonate | | **Mounting Type** | Panel Mount, Front Square (Bush Mount) | | **Ingress Protection** | IP65 (Dust tight and water jet resistant) | | **Termination Style** | Solder Lug | --- ### 2. Detailed Part Breakdown The part number can be decoded into several functional sections: #### A. Mechanical Operation (YB215) This indicates a **DPDT circuit** with a **latching (maintained)** mechanism. When pushed, the button stays in the depressed position until pushed again to release. #### B. Sealing & Protection (CW) The "CW" designation indicates that the switch is **Power Rated and Splash-proof**. It includes internal O-rings and a seal that meets **IP65 standards**, making it suitable for environments where moisture or dust is present. #### C. Contacts & Plating (CP) * **C**: Silver contacts with gold flash (good for both power and low-level logic signals). * **P**: Indicates a rectangular or square body style with specific terminal orientations. #### D. Illumination (5F) This refers to the **Green LED**. The "5" typically denotes the LED brightness or voltage series, and "F" is the color code for Green. #### E. Cap and Filter (JS) * **J**: Clear Cap. * **S**: White Filter. This combination ensures that the Green LED light is diffused evenly across the surface of the button. --- ### 3. Application Use Cases Due to its rugged construction and DPDT configuration, this switch is commonly used in: * **Industrial Control Panels:** Controlling dual circuits simultaneously. * **Medical Equipment:** High-reliability requirements and easy-to-clean surfaces. * **Communication Equipment:** Status indication via the integrated LED. * **Transportation:** Dashboard controls requiring splash resistance. ---
