The **YB215CWCKG01-24-FB** is a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. It belongs to the YB Series and is specifically designed for panel-mount applications requiring environmental sealing and tactile feedback. --- ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Alternate Action/Latching) | | **Contact Rating (DC)** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Illumination Type** | LED (Bi-color or Single with Resistor) | | **LED Voltage** | 24V DC | | **LED Color** | Green (F) / Amber (B) Combination | | **Mounting Type** | Panel Mount, Threaded (16mm hole) | | **Ingress Protection** | IP65 (Dust tight and Water resistant) | --- ## Component Breakdown ### 1. Actuator and Bezel * **Shape:** Round, flush-mount design. * **CW Designation:** Indicates a "Panel Seal" construction. It features an internal O-ring and a rubber sleeve to prevent liquids from entering the switch mechanism or the panel cutout. * **Material:** High-quality resin, designed to resist chemicals and wear. ### 2. Electrical Contact Mechanism * **Gold Contacts (G):** The "G" in the suffix indicates gold-plated contacts. This is critical for **logic-level applications** (low voltage/low current) because gold prevents oxidation, ensuring high reliability in signals under 28V. * **DPDT Logic:** This switch can control two separate circuits simultaneously. Since it is "ON-ON," it toggles between two states and stays in the pressed position until pressed again (Latching). ### 3. Illumination System * **24V Internal Resistor:** Unlike standard LEDs that require external resistors, this model is rated for **24V DC** directly. * **FB Color Code:** This specific variant typically uses a Green/Amber filter combination, providing clear visual status indication even in brightly lit environments. ### 4. Termination * **Solder Lug:** The terminals are designed for manual soldering. They are epoxy-sealed at the base to prevent flux or contaminants from entering the switch body during the assembly process. --- ## Typical Applications * **Industrial Control Panels:** Due to the IP65 rating and 24V compatibility. * **Medical Equipment:** Where hygiene and liquid resistance are necessary. * **Communication Systems:** Utilizing the DPDT gold contacts for clean signal switching.
