The **YB226CWCKG01-5F-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. --- ### ## Technical Specifications Breakdown | Feature | Specification Details | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Series** | YB2 Series (Panel Seal) | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Illumination** | LED, Green | | **Cap Style/Color** | Round, Clear Lens with White Filter | | **Mounting Type** | Panel Mount, Front Side | | **Ingress Protection** | IP65 (Dust Tight, Water Resistant) | --- ### ### Component Analysis #### 1. Switching Mechanism (DPDT) The **Double Pole Double Throw** configuration means the switch can control two separate circuits simultaneously. Being an **ON-ON** type, it is a latching switch: when pressed, it stays in the new position until pressed again. #### 2. Contact Material (Gold) The "G" in the part number suffix indicates **Gold-plated contacts**. * **Purpose:** Gold is used for "Logic Level" applications where the voltage and current are very low. * **Benefit:** It prevents oxidation, ensuring high reliability in low-power signal switching where silver contacts might fail to complete the circuit due to surface tarnish. #### 3. Illumination (5F-JB) * **5F:** Represents the Green LED. * **JB:** Indicates the physical cap style—a clear lens with a white shroud/filter to diffuse the green light evenly across the button face. #### 4. Environmental Sealing The "CW" designation identifies this as a **Panel Seal** model. It includes an O-ring and a rugged housing that meets **IP65 standards**, making it suitable for industrial control panels, medical equipment, or outdoor kiosks where exposure to moisture and dust is expected. --- ### ### Typical Wiring Pinout The switch typically features 6 terminals for the DPDT switch and 2 additional terminals for the LED. ```text Terminal Layout (Bottom View): [+] [-] <-- LED Terminals (Polarity Sensitive) (1) (4) <-- Normally Closed (NC) (2) (5) <-- Common (COM) (3) (6) <-- Normally Open (NO) ``` ---
