The **YB225CWCKG01-5F-JB** is a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. It belongs to the YB2 Series and is specifically designed to be panel-sealed and tamper-resistant. --- ### 1. Technical Specifications The following table breaks down the core electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Circuit** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Contact Material** | Gold (G) - Ideal for low-power applications | | **Illumination** | LED - Green (5F) | | **Cap Style/Color** | Round, Clear Lens/White Filter (JB) | | **Ingress Protection** | IP65 (Dust tight and water-resistant) | | **Mounting Type** | Panel Mount, Front Square/Round Bezel | --- ### 2. Part Number Breakdown (Nomenclature) Understanding the alphanumeric code helps identify the specific components of this assembly: * **YB2**: Series identifier (22mm body diameter). * **25**: Circuit configuration (DPDT). * **CW**: Shroud/Bezel type (Circular, Panel Sealed). * **CK**: Actuator/Body style. * **G**: Contact material (Gold). This indicates it is for **logic level** switching, not high-power AC loads. * **01**: Termination style (Solder Lug). * **5F**: LED specification (5 = LED type, F = Green color). * **JB**: Cap details (J = Clear lens, B = White insert). --- ### 3. Key Electronic Features * **Logic Level Switching:** Because it uses gold-plated contacts, this switch is designed for low-energy circuits (0.4VA max). It prevents oxidation that typically occurs on silver contacts when used with very low voltage. * **Tactile Feedback:** The switch provides a crisp, positive indentation, ensuring the user knows the state has changed. * **Dual Pole Design (DPDT):** This allows the switch to control two separate independent circuits simultaneously. * **Environmental Sealing:** The "CW" designation indicates it is "Splashproof," meeting IP65 standards, making it suitable for industrial panels or medical equipment where cleaning or moisture is a factor. --- ### 4. Typical Applications * Industrial control panels. * Medical instrumentation. * Communication equipment. * High-end audio/broadcast consoles.
