The **YB225CWCPG01-5D-JS** is a high-quality, panel-mount pushbutton switch manufactured by **NKK Switches**. It belongs to the YB2 Series and is specifically designed to be tamper-resistant and aesthetically pleasing for industrial or high-use interfaces. --- ### 1. Key Technical Specifications The part number encodes specific electrical and physical characteristics. Below is a breakdown of its core specifications: | Feature | Specification | | :--- | :--- | | **Switch Type** | Pushbutton (Cylindrical Body) | | **Circuitry** | DPDT (Double Pole, Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 5A @ 125/250V AC or 3A @ 30V DC | | **Illumination** | LED (Amber/Green Bi-color) | | **IP Rating** | IP65 (Dust-tight and Water-resistant) | | **Mounting Type** | Panel Mount, Front Square (22mm cut-out) | | **Termination** | Solder Lug / Quick Connect | --- ### 2. Electronic Component Breakdown #### A. The Switching Mechanism (DPDT) The **Double Pole, Double Throw (DPDT)** configuration means the switch controls two separate circuits simultaneously. Each "pole" has a common terminal that flips between two output terminals. Because it is **Maintained (ON-ON)**, the switch stays in its new position after being pressed until it is pressed again. #### B. Illumination (LED Logic) The "-5D" suffix indicates a specific LED voltage and color configuration: * **Voltage:** Usually requires a resistor if not integrated; however, the "5D" series often corresponds to a 2V or 5V forward voltage requirement. * **Bi-color:** This model typically features a dual-color LED (Amber/Green), allowing for visual status feedback (e.g., Green for "System Ready," Amber for "Active"). #### C. Contact Materials The "G" in the part number denotes **Gold-plated contacts**. * **Benefit:** Gold prevents oxidation and provides high reliability in low-energy logic-level circuits. * **Versatility:** While rated for 5A, the gold plating ensures it works perfectly even in micro-ampere applications. --- ### 3. Physical & Environmental Construction * **Panel Seal:** The "W" in the prefix indicates it is a **Waterproof** (IP65) rated component, utilizing an internal o-ring and a polyethylene gasket to prevent liquid ingress. * **Cap/Bezel:** The "JS" suffix refers to a silver bezel with a clear/white cap insert, providing a metallic, professional finish. * **Tamper Resistance:** The "CP" designation indicates a flush-mount style which makes it harder to accidentally trigger or damage. --- ### 4. Typical Applications * **Industrial Control Panels:** Where wash-down protection is required. * **Medical Equipment:** Due to the reliable gold-plated contacts. * **Transportation/Kiosks:** High-durability environments where bi-color feedback is necessary for user interaction. ---
