## Overview of the YB215CWCKW01-12-JS The **YB215CWCKW01-12-JS** is a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. It belongs to the YB Series, specifically designed for panel mount applications requiring durability and visual feedback. --- ### Technical Specifications | Feature | Detail | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Circuit** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 5A @ 125VAC / 250VAC; 3A @ 30VDC | | **Illumination Type** | LED (Red) | | **Voltage (Nominal)** | 12V DC | | **Actuator Style** | Round, Flush | | **Panel Cutout** | 16mm Diameter | | **Termination** | Solder Lug | --- ### Breakdown of Part Number Components The part number follows a specific nomenclature used by NKK to define its physical and electrical characteristics: 1. **YB2**: Series designation (YB Series Power Rated). 2. **15**: Internal code for DPDT circuit configuration. 3. **CW**: Housing type (Splashproof/Dusttight - IP65 rated). 4. **CK**: Mounting style (Threaded Bushing). 5. **W01**: Silver contacts (Standard for power ratings). 6. **12**: LED voltage rating (12V DC). 7. **JS**: Cap color/material (Silver bezel with a Yellow/Clear insert). --- ### Key Electronic & Physical Features * **Latching Mechanism:** This is an "ON-ON" switch. When pressed, it stays in the down position and maintains the circuit connection until pressed again to release. * **DPDT Configuration:** Having a Double Pole Double Throw circuit allows the switch to control two separate independent circuits simultaneously or act as a polarity reverser. * **Environmental Protection:** The "CW" designation indicates it is **IP65 rated**, making it resistant to dust and low-pressure water jets, ideal for industrial or outdoor panels. * **Contact Material:** Uses silver contacts, which provide excellent conductivity and are rated for higher AC/DC current loads compared to gold-plated logic-level switches. --- ### Basic Wiring Diagram (Example) ```text [ LED Terminals ] [ Switch Terminals ] (+) (-) (Common) (NC) (NO) | | | | | 12V DC Ground Input Load1 Load2 ```
