The **YB215CWCKW01-5F-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. --- ### 1. Part Number Breakdown To understand the electronic and mechanical properties, we can decode the part number: | Segment | Code | Meaning | | :--- | :--- | :--- | | **Series** | YB | Standard size pushbutton switch | | **Bushing** | 2 | 22mm Diameter (Panel Cutout) | | **Action** | 15 | SPDT (Single Pole Double Throw) / Momentary | | **Seal** | CW | Panel Sealed (IP65 Rated) | | **Terminals** | CK | Silver Contacts / Solder Lug & Quick Connect | | **Illumination** | 5F | Green LED (Super Bright) | | **Cap Color** | JS | Clear/Silver (Metallic silver insert) | --- ### 2. Electrical Specifications These parts are engineered for both logic-level and power-switching applications. * **Contact Rating:** * 3A @ 125V AC * 3A @ 250V AC * 3A @ 30V DC * **Insulation Resistance:** 1,000 Megohms minimum @ 500V DC. * **Dielectric Strength:** * 1,000V AC between contacts (minimum 1 minute). * 1,500V AC between contacts and case. * **Mechanical Life:** 1,000,000 operations minimum. * **Electrical Life:** 100,000 operations minimum. --- ### 3. LED Characteristics (The "5F" Component) The illumination is provided by an integrated green LED. Note that LEDs are current-dependent devices and usually require a series resistor if not built-in. | Parameter | Specification | | :--- | :--- | | **Color** | Green (Super Bright) | | **Forward Current ($I_F$)** | 20mA - 30mA | | **Forward Voltage ($V_F$)** | Typically 2.1V to 3.5V DC | | **Reverse Voltage ($V_R$)** | 5V maximum | --- ### 4. Key Features * **Environmental Protection:** The "CW" designation indicates it is **IP65 rated**, making it dust-tight and protected against water jets. * **Tactile Feedback:** Provides a clear, snappy actuation feel. * **Compact Design:** Short body allows for installation in shallow panels. * **Mounting:** Fits a standard 22mm circular hole. ---
