The **YB215CWCKG01-12-EB** is a specific part number for a high-quality illuminated push-button switch manufactured by **NKK Switches**. This component is part of the YB Series, known for its modularity and robust environmental sealing. --- ## 1. Technical Specifications Breakdown The part number can be deconstructed to understand its electronic and mechanical characteristics: | Code Segment | Feature | Description | | :--- | :--- | :--- | | **YB2** | Series | YB Series Pushbutton (22mm Bushing) | | **15** | Circuit | SPDT (Single Pole Double Throw) | | **CW** | Seal | Panel Seal (IP65 Rated - Dust & Water Protected) | | **CK** | Mounting | Round Bushing Mount | | **G** | Contact Material | Gold Contacts (0.4VA Max @ 28V AC/DC) | | **01** | Terminals | Solder Lug / Quick Connect | | **12-EB** | Illumination | 12V Yellow LED with Yellow Cap | --- ## 2. Key Electronic Features ### Contact Mechanism * **Logic Level Rating:** Because the contacts are gold-plated (**G**), this switch is designed for low-power "logic level" applications. It prevents the buildup of oxidation that occurs in silver contacts when used with low voltages. * **Switching Action:** Momentary (On). The switch returns to its original position after being released. ### Illumination (LED) * **Voltage:** Rated for **12V DC**. It includes an internal resistor suitable for 12V operation, meaning no external resistor is required for most standard 12V circuits. * **Color:** The "EB" suffix indicates a Yellow LED paired with a Yellow Cap for consistent light diffusion. --- ## 3. Physical Construction ### Environmental Sealing The **CW** designation indicates that the switch is **Panel Sealed**. It meets **IP65** standards, making it resistant to: 1. Dust ingress. 2. Low-pressure water jets from any direction. 3. Splashing water. ### Dimensions and Installation * **Hole Diameter:** 22mm (Standard panel cutout). * **Terminals:** Solder lugs, which can also accept 0.110" quick-connect connectors. * **Cap Shape:** Round and flat. --- ## 4. Typical Applications Due to its gold contacts and IP65 rating, this part is commonly used in: * Industrial control panels. * Medical equipment (where cleaning fluids may be present). * Test and measurement instrumentation. * Audio/Video broadcast consoles. ---
